Redline for you.
That was the biggest problem with it that I saw, the muscle was on the wrong side of the character's left leg. When you turn your foot that much, the muscle of your lower leg turns with it.
Something looks kind of off with the length/perspective of the arm on the same side to me, but not being the best at perspective myself, I couldn't redline it successfully.
The rest looks really good so far though. :D
I think it might help to make the shoulders a bit wider. I get the feeling you want a real drastic perspective, but you're head isn't too far from your shoulders so they should still be in regular proportion to the head. C:
Lookin good though ;D Will you be posting more WIPs?
No problem. :D I think you're right about the arm being too small/high - the elbow on it is higher than the other one when compared to the floor line, and it makes it look like she's holding it in a different position to her other arm. And the gap between the arm and her chest seems a little wide, which adds to the problem of the position looking different.
I gave redlining the arm another go to help illustrate what I mean. Nowhere near perfect, as like I said, perspective isn't my strong point, but I hope it helps a little.
: Ooh, trying on perspective too? Looks nice!
It helps me a lot to draw the body as just a lot of basic shapes, like a rectangular block for the torso + shoulders, etc.
Right now, the main thing I would suggest is working on the nose. You're looking from the top down, but the nose is still tilted upward, which is a little awkward. xD I know it's your style to draw noses that point up, but it's still affected by perspective.
