I would like this sig more, I think, if two things were changed:
-the cut. Terrible choice, in my honest opinion. If it wasn't for his tats, I wouldn't know that was Punk. I think firstly and foremost, you need a different choice of picture. Something where you can see his face a little more.
-Text. Not too bad a choice in text, in my opinion, but bad placement. Looking at it a second time I didn't really like where it was sitting, as it just seems ... 'out of place'.
Those two things are possibly the biggest things you need to look at firstly, again imo. Otherwise I don't mind the look of it. It's simple, but still doesn't look too bad.
