You are simply bad arse. I love how the background mixes with the texture and the roughness of the armor and how you made the effect on my name.
Pretty good, but everything seems a little too scrunched in there. Also, I say brush with a splatter brush and blurr to add some sort of depth.
agree with danger mouse here, it looks rather flat, and I feel like its just too busy. Too much going on for not enough effect. Try to be a bit more minimalist in my opinion, really optimizing how you use a few effects. For example, my sig is very simple, and effective, but I used very few effects/brushes etc to acheive the effect. I'm not a PS pro, but I see this falling into the trouble that many sigs do: being overly busy with extra crap that doesnt ADD anything to the actual finished product.
The "duel weilder" text I'm not so crazy about and it's way to sharp. Well the stock/render is. Smudge or blur perhaps? It's a good sig all in all though.
