The Champion colored cover

I know I should be working on other artwork right now, but I couldn't resist coloring with my new programs I just got!
I just got the CS6 package and I love the new programs I have. I even have flash, so I can start animating!!!
In the meantime, this is my first time using the newer version of photoshop. If you're reading this then can you give your opinion on my pic? Anything I need to improve? Should I color in all the covers for The Champion?
Aaaaaaaaaaand . . . . I start school next week, so I won't have as much time for my artwork on DA, though I'll still try to update every friday.
