Looking good seems to be a a Sonic Station, headphones at the ready.
About that central decal, it looks rather cool, though perhaps you could make the black blacker for a fully transparent effect.
I use http://www.xnview.com/ to do that kind of thing it's free and simple to use. Image > Adjust > Levels, then adjust the black point until all the blacks go completely black and your set for full black transparancy.![]()
exactly what do you want done to it? do you mean the blurry edges? I can crop it for you if you want and clean up those edges...
