Looking for a bit of help

[modblot]

I think the problem with the finished piece is the lighting is confusing. It looks like the light is coming from top-right, but there are several spots where it suddenly looks like there's an equal, 2nd light from top-left. There's also spots where a drop shadow just isn't there, like from the arms onto the body. 

If you want, I could try to do a quick paint-over to show where some shadow might end up going.
