Title, Cover, Blurb

The title is fine. One word titles definitely work, and I like them. 

The cover looks OK, but I would not have clicked it on the wild of wattpad. It looks a little cheap, just a bunch of images put in a collage. I think you should just stick with the middle image and remove the other ones. Best to get someone good at making covers for your book. 

The blurb... is just not catchy. 

But he's not powerful, either, and we're losing. Another one sucks a breath in to torch me. I squeeze my eyes shut. Suddenly, I hear an earth-shakingly loud and angry roar. I look and see a blast of white, silver, and blue being shot at the dragon tormenting me.

"Leave them!" my saviour thunders.

A blurb's job is to introduce the characters, plot, themes and genre. Your blurb does not tell us anything about the story- it's just a scene, and we know none of the characters, so we don't really care about the scene. I definitely think you should update it, but it's really your call, if you want to be vague for stylistic reasons.

Writing

Your use of language is good. There are very few errors of 'English', or none, and the meaning was usually unambiguous. However, some parts felt confusing to me.

This could be due to several reasons. You take a little too long to describe something that is not very relevant to the story. Descriptions are best short and vivid. Another thing is (a plot problem) I didn't really understand what type of story you wanted to write- as a result it all felt kind of dull to me. I didn't really get to the heart of the story. I know the characters want to be safe from 'Hunters' and there's a war going on, but I never felt the threat. I didn't understand their goals or motivations. 

(However, I'm just one person. Maybe I'm just dumb. You should ask others if they feel the same way. If 50% of them feel the same, maybe you should consider this)

One common problem you faced was the you didn't put a new paragraph for a new speaker. Also, your prose, although good, was basic and not vivid (nothing wrong with basic, and it is realistic, because MCs are just teenagers. However, it did bore me)

Also, you had a bit of melodrama. ('Ignoring me even though I'm starving to death in front of them', the scene where a bunch of characters die). Not a huge issue, though. You can fix it later by, primarily, showing. 

Worldbuilding

There was no info-dump of world, which is quite rare actually! Good job on that. Your opening line, where Durpner was told not to 'act like a human' did a great job of introducing the world and character. 

However, as stated before, try to describe things efficiently and vividly. This is very important for fantasy, because no one knows what your world looks like, and probably also your fantasy characters. (At first I though Dracoponian was a boy, then thought he was a two feet baby dragon- is he one though?)

I think the characters' magic should be introduced a little earlier. I went a chapter thinking Shadow was human and normal (you could have mentioned the wings earlier). 

The scenes did not ground me in your world (due to descriptions, again). Showing was rarely done, and you heavily leaned on telling (a big no-no in particularly fantasy. Showing is ideal for worldbuilding and emotional scenes). 

Plot

I've mentioned this before, your plot did not deliver the promise and progress too well. 

The plot consists of the promise, the progress, and the payoff. The promise is you giving some indication of what your story is about (The promise of Harry Potter: A tween boy finds a magical world and attends a school of wizardry). You did indicate that the characters are on the run, want to stop the war, and they're hiding... but I felt like the message was just 'told'. (did not feel the threat, felt little for the characters).

The progress, though, was the major issue. I did not feel the plot was moving. It felt static. I felt like nothing was happening. (Can't pinpoint why, but I think it's because I'm not clear on what your characters want).

The conflicts should be introduced better (instead of the character just outright saying them- works better in animes, not so much in books!) and I didn't feel the stakes. 

Characters

I have a lot to say about the characters...

Firstly, you distinguished Vapor's voice very well from the other POVs. Great job! Vapor's voice was really the strongest, then Arkera's and then the others. 

As mentioned before (I'm so sorry for the repetition, it's just they all affect each other) I didn't feel the characters goals and motivations, their wants and needs. These were 'mentioned', not shown. 

Although none of the characters were stereotypical, none stood out to me (except Dracoponian, I will protect my adowwable tiny dragon (that's just how I imagine him, correct me if I'm wrong of course) at all costs). So, can you like, give Dracoponian his own series- (just kidding, it would be really hard to since he doesn't talk. I would read it though...)

Also, I couldn't really 'see' the characters (no vivid descriptions) and their backstories were very 'tragic' but cliche (Pretty much all fantasy characters don't have parents. I shouldn't complain, because I did the same... but I do want you to know that I did not enjoy reading the backstories. I felt nothing when they lost their parents. Because I didn't care too much about the characters in the first place, much less their parents...

So overall, you just need to make your characters more 3D and unique, and make readers care about them (Save the cat is the simplest method- you did this for Shadow, but not the others. Well, technically you did make us empathize with the characters because their parents died, it's just I'm evil and I didn't feel anything because of *~sHOwiNg~*

... One more thing. The mass murder you committed, Needletail. We need to talk about this. You can't just kill three people in one chapter! I'm calling 911-

(On a serious note, I don't agree with 'you can make a character just to kill them'. Don't give them names if you do. When the characters died, I didn't even care, because you didn't really give us a reason to. We didn't know them. They were just mentioned once and only because they died. Even the MCs seemed to recovers shockingly quick...)

I know I'm pointing a lot of things out, but remember: Your voices were well written. It's something many newer writers struggle with. So well done! 

So to summarize my long-ass review: I didn't feel anything. 

But it does NOT mean your book is bad. The major problem is TELLING instead of showing. If you fix that,  60% of all these problems will be solved. 

(I know you're editing your book right now, so good luck with that! Hope you write that revamp of Shadow. Definitely want to see how far you go, because- I'm a nerd for fantasy). 

As always: You are the author and only you know what's best for your book. You don't have to do anything I pointed out, because only you know what kind of book YOU want to write. Good luck!
