Pepo, it looks absolutely amazing. I can barely draw a stick figure, but can I give some criticism too? I know some people like to hear
some criticism as well, as to improve it or consider the critiques for later works.
1. It does look a bit sad. It doesn't have to be enraged either. We don't want it to "dive" off of a bridge though...
2. The length of the body looks a bit short. Is that because the point of view is a bit angled? The head makes it look like a side view, but the body reflects an angular view.
3. It looks off center, but I think you were trying to show the full wingspan. A little bit more of the wing going off-image wouldn't have hurt if it meant the pegasus would be centered.
Take those criticisms with a grain of salt, because I'm no artist. Still, it looks incredible.
