My life at the boarding school @Uditasree

Cover:
Your cover is fine and presentable, however as a graphic designer, I would say your cover needs a bit of work. From you title, I'd presume , or better said envision to see a girl with a backpack (to represent that she is a school girl.) walking somewhere (it could just be the background you're using now.) or a girl with her back to the reader dragging a luggage behind her and heading towards these big gates. Let me know what you think! But in general don't worry about it as it looks attractive, just doesn't go with your story.

Blurb:
Your blurb is clear and straight forward, however I believe you can make it a bit better! A blurb is the first thing a reader will see so you  have to ace it! Your on the right track, but I think you need to add more and rearrange some words.
Maybe something like this: it took one boarding school to change Sara's life, one school and three people, Harry, Ellie and the (an adjective to describe Ronald) Ronald... a story handcrafted with memories and adventures.
Do you get what I mean? Of you need more help just let me know!

Characters descriptions:
I really love your introduction chapter! You don't give too much detail but definitely enough! I know what to expect and look forward too (I already have a favourite character lol). As a suggestion, I'd say, maybe you would like to give each character a quote? I'll give an example: Ronald: "My silence is the essence of my intelligence." Or "minds writes more than ink." I like how you slowly allow the reader to discover a character.

Storyline and plot twist:
I really like the concept of your story! It's heartwarming and enjoyable. Some chapter really had me laughing! In my opinion I think you can spice your story up a bit with some adventures! It could be in school or even outside! Maybe a character can discover something? Maybe a complicated past?

Dialogue:
The dialogue is kind of minimal on you book. The dialogue you had was funny and realist and I loved reading it! I would really love it if there was more dialogue. Dialogue is sometimes the way readers discover the character, by adding more dialogue, you'll have your readers down in your words and really understand your characters.

Language choice and vocabulary
You have a very interesting way of describing things like for example friendship. I think you can replace some words with their synonyms to add more depth to the story. Your vocabulary is  okay however I think it can be improved! I also think you can add a few different language techniques, ie personification, metaphors and so on.

Grammar and spelling:
I've not seen any spelling errors and that's amazing! In terms of grammar, I'd say you might need to take a look at punctuation. Punctuation may not seem very important but it plays a vital role in a book. With a bit of proof reading, you book will be sparkling!

Reader enjoyment/ overall:
Your book was enjoyable and I definitely had a good laugh! Keep up the great work!
PS: I like Trix she's funny but I like Sara more!
