Not too fond of how Mugen and Jin's details look blurry. The extraction needs work because I still see some white edges around the scan. Maybe you could vector/reCG them to make their details more defined and to fix the extraction problem? And...well, there are a lot of things about this wallpaper that I don't quite get (pardon me for being so slow). Did you intend the Mugen and Jin picture to look like a painting or something like that hanging beside a scroll? Or are those pretty japanese patterns a frame for your image (which doesn't really work, if that's the case)? I like the background behind Jin and Mugen, though I'm not sure if you intended that thing behind the text to look sliced into pieces. =/

Oh, and please compress your file. The file size (2.04mb) is extremely huge for 1600x1200. I don't think it's going to hurt the quality of your wallpaper if you compressed your file a bit.

Very nicely done, I really like the concept and the cloth-patterns you used in this wallpaper. My only complaint would be with the text and images behind the characters, they're a bit overwhelming and tend to down out Jin and Mugen (who are very simple looking and are easily drowned out). Overall, fantastic job though.
