Hi Sadira, welcome to CA!
I 'm liking your piece here especially the pose design of it and the negative space shapes.
I think I get what you're trying to do with the black shadows but I don't think it's working, especially on the face. Instead of her coming in/out of dark shadow it seems more like some black entity is starting to smother her. Did you have the photo like that...with a real high key / low fill lighting set up?
Some other issues I see are the nose construction, the halter top doesn't feel like it's wrapping around the form and the hair seems outta place with the more graphic design of the rest of the figure, especially where it goes into the shadow area but not affected by it.
I don't think it would take too much to work on these things and I'd like to see this piece finished up!
You are a level 8 ninja and even though you have a lot of weapons sometimes your ninja moves are your most powerful.
