I love the wallpapers we see over at http://theartthearttheart.com, so I decided to try one of my own. It's definitely not on par with what has been produced for previous wallpapers, but I thought it turned out well, so I wanted to share. I'd love to see some other wallpapers people have made for the game.
Now in a mobile size!
EDIT: Per suggestion, I've added a version with more subtle team logos.
I'm not amazing at cropping to proper widths for average users because I use my TV as a monitor @ 1920 x 1080. I did make it smaller, so hopefully it looks ok and doesn't take up the whole screen in the preview. Let me know what you think. Thanks!
EDIT: Thanks for all the feedback. I did another, just in case those of you who like variety haven't gotten your fix anywhere else.
EDIT III: Ok, the high res are up thanks to imageshack who, it seems, is the only major image-hosting service that doesn't down-size your high-res photos. Anyway, enjoy!
