That's a very impressive codpiece.
On the banner/signature image, I've never been a real fan of the use of over-crowding brush strokes on something as small as a sig, it kind of hides the warrior. A neutral background with some understated flair would be better, I my opinion, of course.
Surely though, that's what art is all about? It's definetly not a tent filled with the names of random men you got drunk with for no reason
