Pixelized

Too much?

Spoiler:

I'm personally not a fan of the effect you used here. It makes your render look low quality. The large black thing behind the gun that is in the Spartan's hands, along with the gun on his back being so focused on, ruins the flow of the piece. I'd get rid of that shape behind the gun and then blur the background and the gun to provide some depth. I like to Apply Image then use a 0.5 Gaussian Blur on the entire tag, then erase around your focal and lower the opacity of the layer to 40-70%

Unfortunately, I didn't save it as a n editable file, so I can't do anything to it now... I did do a different one though (stealth advertising ; )

The black thing is part of the stock, I didn't realize how bad it looked until I was 90% done with the sig, honestly...I was too lazy to go all the way back to like 40% completeness and do it again :P

Love your sig by the way (:
