Good job my friend, I like almost all of them but the one that I like the most is the first one, the one of Alex Rodriguez, I love the background and the picture you have selected for the sig. Nice work and hopefully you'll keep showing some more of your work. Keep up the good work.
The A-Rod one was my most recent. I made it for a contest that never happened. Anybody can wear these is they like, just give credit. But don't expect a whole lot of updates. I only make sigs on weekends during the school year because of both school and work.
