Okay, here it is.
Da dadadaaaaaaa!I had more time and I kinda went a little too crazy, so I included a version without lighting as well as a posterized (less detailed) version that may be less laggy. You can use whichever you want, just have fun with it. And if you have gimp, play around with the source until you have the results you want.
P.s. can I remove the other background from my dropbox? It's kinda taking up extra space, but I didn't know if you were done with it.
