For example look at this LoL lobby, its dark and looks amazing, but it has no static colors, what I mean by ''static'', everything is gradiented and everything blends in, unlike gunz (all) lobbies where the majority is one color.

The panels should be more transparent and under those should be a picture of gunz stuff

thats just my opinion though, BUT all popular games blend as many textures together as possible to make the interface look like it has some life in it.
