The art is okay-the legs seem a bit wonky, but the colors are bright & the face has character. However, the waist up was clearly referenced from Zeronis' Tracer art: [NSFW] http://i.imgur.com/cfLvMHh.jpg
Why didn't you credit him for the pose you referenced? It's not exactly 1-to-1 tracing, but you still drew over another artist's work.
