I would lower the displacement effect overall. I really love what it did around the football and fingers like Met said, and a couple of other places (light streak on far right side is one of them) however, I would add a layer mask and reduce the effect on the rest of the sig a little bit. The font really isn't that bad. Actually its a really good font its just the placement of it isn't quite right. Not sure why though.
For most of my sigs, I tend to use either Arial or century Gothic or Impact. Nothing really fancy most of the time, just effects and placement is what makes really good fonts.
