nice drawing, just a few points of taste:
the lines in the skin make it look a bit to twisted, like its part of the cloth almost. missing at least a bit more of the right arm, it looks like a one armed beauty (though that might be the hole point of the title, if i get it) its fine as it is, but a bit of background would show a hole story, since it looks (in my taste again) as a very sexy and talented dancer from here. it could show so much more how ever if we push imagination just a bit more. very nice light use, poseing, face expression. al together a 10/10, just points of taste.
