Something about my image is off. Help?

[C e r u l e a n]

I've been working on a contest entry and although the original concept was pretty good, at least I thought so anyway, after coloring it, something about it looks off. Can anyone help me?

Here's the link to the rough sketch: Rough Sketch

Here's the link to the colored piece: Keep in mind I am far from being done.

For me, I think it has to do with the perspective, her hands and the way it is positioned. My sister thinks the entire pose is wrong as no really stands like that..but I think it's possible. I want to show that she's both fierce as a warrior and an artist.

I'm not sure but to me it seems that her legs are a bit too big/thick, which gives the impression that she is leaning backwards.

I have to agree. The proportions are off. The top half (ribbon up) is small and a little dis-proportioned. The angle of the legs seems to be looking at a high perspective which would mean her top half should appear a bit bigger and the bottom smaller.

This picture shows a person standing taken at about belt level
This one is taken a little higher
This is a person sitting

Based on the angles in your drawing it seems as if the feet are drawn in a way similar to a person that's sitting (or at least the perspective of something much higher). If you look at the angles of the standing people's feet you might be able to correct that.

I think the concept is pretty cool.

Thank you both so much! I see it now! I'll get to work right away and come back and post an update.
