At first glance, my main problem with this was the sudden blending into his arms and the bg. I looked at Jericho then TRIED to follow his body out to his arms, and it was actually after a harder look that I saw where they went, lol. So that was my first problem.
I personally don't really have anything against the greenish finish over Jericho, or the colour of the sig for that matter. Yeh you could prolly pick better colour schemes, C4s example has it's up's and down's as well, but this is the case for most sigs.
The border I'm not a big fan of, I think a simple 1/2pixel black and white border would've been fine. This one seems a wee-bit too thick, imo.
A random note - idk what it is, but there's a brush on the right hand corner, like a corner piece of something. Get rid of that, really ruins the flow of the sig.
Otherwise I like this. Dont take too much personal annoyance at this, just all our opinions.
