I like what you've tried to do with the Steven Gerrard signature. It looks much better as a signature as the light texture you've used just isn't eye candy enough when made larger.
The sig you've posted above is very creative. You certainly like to take chances; much like myself. Keep on trying new things as it gets a bit tedious when people make signatures in the same style because it looks good. This may be just for fun and that how I started. However, having shown my photoshop work to my art teacher, I was deemed capable of being an IB Higher Level Art student

I don't know if you're on footiearts, but you should register. They
will criticize your work but it makes you work just that much harder the next time.
