it looks nice but also the background needs to be smoother imo maybe blur it a bit to smooth it out or something because to me it seems to sharp =x
yeh definately break out the blur tool on this one mate, by doing this u will implement some decent depth perception as well by bringing the focus into sharper releif as opposed to the rest of the background...
#3 is the best imo get rid of that c4d next to his arm tho, it's killing the sig. other than that, very nice sig good job.
