Maybe do a slight add noise to the photo ONLY and radial blur with it set to the circle one...again, to the photo ONLY!...
The text "Slipknot" is nice but I'd make it a bit bigger and same with the other text...
It looks good, and optimize the colors and stuff, if you didn't already...
Here's another idea, make only the photo grayscale...that way, you can leave the font small...cus it'll stand out enough....duh
Oh and I hate Slipknot, but I really shouldn't be saying that hear cus you'll beat meh up...noo don't!
*fixes his thick nerdy glasses*
Keep workin!
