I like this alot, it looks so good in the thumbnail and so blurry in the actual picture. I think an image with open outsretched hands would look better then the one you have, where the guy is kinda pinching the thing.. a render won't be too hard to find for that. The bg looks nice, i actually prefer the colours you chose, fits well with the.. fractal?

If you used a brush for that fractal ... then that's the problem =| ... try making one in apophysis

^_^ ... if you did make it in apophysis render it bigger / better quality
