Girl, you've said it all. You've given all the possible criticisms that came to my mind and I can't think of anything to add.

With that in mind, at least you know where your drawing's defects are therefore you can do something about them.

Unlike me, I'm usually blind to the errors of my creations so I don't know what's wrong with them until I get a criticism.

EDIT: I just saw the reply times now, so I have something to add. The coloring you did isn't too bad, considering you only took a few minutes to do it. I can never color something that fast and still come up with something that resembles my original work.
