Well, the main flaw is that the focal point should've either been his head or his card... but since you've been scratching and blurring them...
His tail looks bitten too
What i like are mostly the background and
those tiny horizzontal lines you've added on top of him.
The rest is no good tho i'm afraid. :s
By the way, thank you for finding a render, i should remake my own now but i'm afraid i'm too lazy to. x)
Maybe in some time i'll give it a whole new spin altogether.
Actually depth is one of the few things done right: there's clearly some place behind the render.
Btw, your post is quality hypocrisy. x)
