Gonna be honest(imsorry), it's a 4/5 for me.
It's good don't get me wrong, and it does it's job. It provides me with the idea of your character and what he's about, and the tags below help out as well. I just feel that the image, could have a little bit more added to it. But that's just my view. Nonetheless it is a good signature. I do like the very very small border it has, it looks quite nice.
