This skin is perfect but i think reflections can't be show its back. Am i right?
Yea I agree, but theres not much you can do about it other than make the top album art transparent too, or you have to have a layer behind the album art on the bottom OR if you could do like a mask thing like in photoshop and have a gradient from bottom to top of reflection area it could pull it off...
Edit: If you could do a layer mask effect in winamp it would be a special plug-in-esque feature. <--Hard to explain.
