Love the line work quality and detail of the character. While the character's style and detail is fantastic and graphic, the background is the weaker part of the image. You are definitely capable of very impressive and awesome art, and if you put a little more into the background, it'll definitely be an awesome and stylistic sight! Enjoyed the concept of depth by making the background blurred out. Depth being added to a graphic style like this is rarely seen, and it's a cool, rare concept.
Great work!
