Just above His head to the left, rquires a C4D or Such. it looks a little empty.

think it looks wicked, i love the colours and flow in it, it really looks like theres movement in it.
perhaps darken the right hand side a bit more to give the shadow against the light source.
yeah as Bob suggested, in the centre of the sig theres a "flat" whiteish spot, try putting some sort of movement effect in there to continue the motion in the sig.

a border (it looks perhaps as though theres a 1px transparent border but cant tell too well)

I kinda like it, it just need alittle something behind and when i first lookd at it.. "WHERE IS THE TEXT!?" "oh theres the * little text." The text could have been bigger
