I've really liked all the stuff you've done so far, this included. I think you have a real talent for this. Your art is clean and consistent, your jokes are pretty solid.
One thing with this though, and take it with a grain of salt because it may just be my own confirmation bias, but this dude reminds me of Deadpool, in both how he looks and how he talks. The last panel thing is like his 4th wall breaking deal. But, like I said, I tend to see Deadpool everywhere, so that may be my issue.
Edit: And a free joke for you if you want it (or if it wasn't intentional). Gold is one of the softest metals around. So, you know, soft skull, brain damage, etc etc.
