I agree. I think the text is in the wrong place. Try making the text blend in slightly by the guys face, just under the right blade, and follow the line of the blade with the text. Make it so that it takes a little while to see the text. I also think that it is a little empty in the top corners, sombody else comment on that though :3
Try to make a little better quality sig, because now always when i've seen sigs by you are all very grainy...
and what is that sharper color in the left side of his head? o_O
also i dont see much time invested in this.
