Alright, here are my two cents.
¢1: There's leftover black strips (you know, where the minimize, close buttons are; what's the technical term?) above the program windows, plus, there are Vista buttons.
¢2: I'm still not too keen on installing other programs to do something I can just do in Windows' default control panel. I'm picky on how I set up my themes, but I'm also not too picky on what themes are actually available. I'll sacrifice a few extra million themes that I could download if it means I don't have to downloaded extra programs and install them to set the themes up. I was quite content with just the Windows XP default and the Windows classic themes, and Zune was just a little "gift" I wasn't expecting. I know you put effort into this, but my personal computer fashions are just not into this. Mabey someone else could enjoy your themes.
