It is nicely done. Some areas it is slightly choppy. Nothing we can't fix while using the render. I say GJ! I just want to tell you something though because I see this a lot for some odd reason. "Render the picture to your saticfaction and then after you think it is done take a black background or another color to see if you still have spots around it." It is good but you left stuff floating out in space. Just a new layer that you can delete later... just with a paint bucket... GJ though.
I thought some parts were choppy. The hair I thought was really choppy until I checked the original and noticed it was just how it was.
