It looks very sleek, the only downside is that it does not seem to be very friendly when it comes to large collections of movies. But then again that is a normal problem for most skins.
The rounded corners of the DVD cases in icon view look sooooo good, would it be possible to have an option to have those in film strip view, im guessing you are using a black mask so we would have to disable fan art but it would look wicked.
wow, props to infinity loop for the video, looks very cool!
btw - the skin also looks good
I think this now playing screen would be nice with faded artist image fanart in the background as alternative option.
EDIT: you could also add an animated transparency overlay that varies the transparency so it has waves/ripples of transparency over the fanart background in time to the music, kinda like what your currently doing with the blue animated background.
