This looks gorgeous. Honestly, the first thing I noticed was the beautiful background. You have this art down, in my opinion. The eye seems to pop out, as it doesn't have any shading. That can be good if it was intended, though. Incredible job, overall.
Love the lighting, love the shading if anything could be changed I'd say adding a bit of a glow around the eye so it wouldn't look like it was drawn on a layer on top of the body layer all in all it's amazing good job
