I know I've seen this before. I'm pretty sure I commented on it too...Anyway, I think this is just excelent, from the way the hand blurs because its not in focus, to the style of the drawing, to the coloring. It's all fabulous. Great work.
If you saw the original work with an unfocused hand you'd want the hand blurred again. It looks too lpain with everything in focus and unrealistic. With the blurred hand it gives the work an manual focus camera feel to it. Trust me...the hand is better out of focus. Actually..everyone I've ever shown it to loves the blur affect except you.
Codename is right... you should have blurred his body instead of his hand. But otherwise, very manga-esque! I still think of big eyes and small triangle noses and small mouths when I think of manga though... I think this is a style in it's own, even though it's used by many people. I like working in this style though. It's simple and it gets the point across. Thumbs up to you.
