The two-toned coloring and the linework is looking nice. However, there are some issues with her proportion and foreshortening. And again, I must point out the arms; they are too short. A lil trick for determining how long to make the forearm: Your foot is the exact same length as your forearm, from wrist to elbow.
When doing complicated poses like that, where the character is leaning their weight onto one leg and the camera is at their hip level, it helps to have someone model for you. That way, you can get a feel for how their legs work at that angle.
Alrighty. Thank you for the criticism. I tried to extend the arms for my next character, and improve other parts, and this was the result:
It's still in progress; just posting the WIP just so I can actually try to get honest criticism so I can fix the mistakes before I begin shading and add the background.
