I don't like wikis having backgrounds in general. At least not awkwardly tiled like this one is. Also the whites/light greys on black is a really stark contrast. That could be fixed by making some of the tones darker, but then it would be almost a clone of the CPW skin.
The red was faaar too bright and made the wiki look like CPW's punk brother, tbh. It doesn't need to be a clone of CPW but Jesus Christ, at least every once in awhile we need to deviate to something else. (Not to mention I've been bitching about it for almost a full year. CPW at least changes it's theme now and then.)
