I was also thinking of doing some combination between gargoyle and cougar/lynx/big cat. Not sure if I can draw that though...

Hmm... constructive criticism mode, activate!
Overall, I like the design, though I feel that she looks more human than gargoyle. I think the legs and arms look great! Feet and hands are alright, though perhaps a bit monotonous in this pose. Tail's fine, but maybe a bit plain? Might wanna check the wings; they look a bit funny. Won't comment on head since you're still working on it. (Nice hair, though. Y U MAKE ME JELLY? I can't draw hair worth anything :s) Clothes are sweet!
I'm seeing ya with your old Umbreon colors. D'ya have a plan for the colors yet?
Anyway, as a whole, I like it. :D

And jeez! REALLY good job drawing that finger. It looks SO realistic! How'd ya do that?? :P

I feel like for this one, I'll have to learn to draw lean muscle really well, something I'm kinda terrible at. I feel like if I fix the head or go with the gargoyle/big cat mix, it'll look a little better. Have you ever seen that episode of Batman the Animated Series "Tyger, Tyger"? Something like that for body but with gargoyle feet and wings? Iunno yet. Yeah there's hardly any detail other than what I know i want for sure.

I think I would like my old umbreon colors, not sure if i'll keep them or go full revamp.

Still in the works but I appreciate the criticism! ^_^ it helps a lot.
