azalea- Wow, I love the lines <3 The face is gorgeous too :3 I think the limbs might be a little short, but I could be wrong.
kat754- I think the far back leg should be more forward then the other back leg, but I'm not sure. Also, it might look a bit better if it were centered in the oekaki so you can see the whole tail ^^;
Shiko Hayashi- That's a cool concept ^^ I feel like the dragon's neck gets too thin though? Maybe just fill that little triangle of black in the corner x3 Also, with the neck area being lineless(or looking lineless) the hair might look better if you erased the lines for it too?
Alexander White- That's a cool concept. I think you're supposed to comment on other's work when you post though, just saying ^^;
Bast- That looks really cool, the muscles look really good ^^
