I like it a lot but it doesn't need the text because it's behind the emulator names. Also you can't use it as the default background because a lot of CFW users are going to be bothered every time to replace it with something else. This won't be because it doesn't look good but because it isn't what they like to have as a background.
I do like the idea of replacing the wallpapers in the firmware but I think that it's better use a set of good looking backgrounds with different colours like we've got on the Dingoo A-380. My idea was to use the dingoonity logo in the background as if it was pressed into it. I think this can be done when using transparent.
That's my idea but I never found the time to make them because I'm always busy with something else.
