Thanks for the advice :) I need to improve anatomy anyways; I'm sorta bad at it.

When I'm done, I'll edit this and let you know so I can see if I did it right this time. :)

You're improving =)

You have the leg anatomy wrong, folding backwards at the knee. Copying the wings was lazy! ;)

Shading is a bit inconsistent: light comes from upper left on the head and tail, upper right on the leg; wings cast no shadow.

Outlines of the wing 'fingers' are a nuisance: they take up precious pixel space that should be used for shading instead, they make those fingers too thick, and create a lot of banding. (there is slight banding elesewhere too, as in the tail)

Palette: good hue shifting in the greens, but the bluish greys don't fit well: they are not 'connected' to the greens. More about this here. You might try to give those wing webs more interesting and contrasting colors like reddish or purplish, provided you bridge them with the greens.
