its to monotone and i can't find the render quicky so work on the focal point also the depth could use some work but mainly the problem is you coloring and lighting source (and the focal point problem) but i like the idea and style you put into this signature good job hope i helped and keep up the good work
I agree with prox 110%...also I think if you did something with that lighting and got a better compo, the gradient/coloring wouldnt be so bad. It looks like it has potential to be a good piece, just needs some work.
I think he went for the mono color... I think it looks good though. To get a better focul, Sharpen the render. Use the blur tool to blur the bg. Don't blur the bg too much though or it'll look bad. Maybe "slightly" burn some of the shadows on render as well. Try that. It'll look good. there's a few different ways to get a good focul, but this one's an easy way. Still looks pretty good. Just work on that focul mate.
