Here is the requested claw tutorial. There's a few different views in here but we're going to start with the basic side view. 

1. As always, start with a circle. Remember to draw lightly. 

2. Now draw a second smaller circle in front of it, with a line connecting them. 

3. Draw the claw shape around the circles. It kind of looks like a dragon head lol. I guess this is how I draw dragon heads... hmm. It will turn into a claw I promise! 

4. Noooooow it looks like a claw. *smiles triumphantly* Just extend the toe into the foot/wrist thingy. 

5. Draw the claw at the end of the talon/toe. 

6. Now draw in the second toe, in front and behind the first. 

7. And put in the claw. 

8. Now go over it in darker pencil/pen and erase your sketch lines. 

And voila, you're done your side-facing dragon claw! I shaded mine in with pencil so here's a pic of that: 

Oh and it occurred to me that dragon claws can have another joint, so I sketched it out to test it. I didn't take process photos but it's literally the same thing as the claws above just with an extra joint in the middle. I think they both work it's really just personal preference. 

I know this is just one view but I hope it was helpful! Also I have more claw views but they won't all fit in this chapter so I'm going to put them in the next one. So I guess I'll see you there!
