Mike,
I dig the area where you did these shots! All the local bands here in LA seem to favor alleys and more urban local for their shots... make you miss trees.
Anyway, the problem I see with the first of your two most recent shots is the contrast problem you'll face on your face. Unless your fairly handy with Photoshop where you can go in and mask the area that needs more definition and play with the contrast and brightness, this will be a tough shot to use.
I think the second of the two is probably better. That green field is awesome. You could do some playing with the contrast settings to really give it a cool glowy effect. I'd also suggest if you do go with that shot, see if you can crop it so you're not dead center, or add some larger text to one side to give it a little less balanced look. I also REALLY like the Manitoba signs in this one. Isn't there an IHL hockey teem up there called the Moose? Anyway...
I through this together as a thought.

Just my 2 cents. Good luck and let us know what you decide on!
