Hey nice sig but like you said, it's a little overdone on his body. And I don't seem to be able to see the words on his left weapon too. It's just kinda bright. The font matches the background really nicely.
I'm not really good at making sigs yet but I can tell your sig is appealing. But the
lens flare on the body is a bit overdone. You'll score higher with that settled. The words on the weapon itself can't be seen clearly too.
Wait till more people gets online and you'll get more comments. =)
