Come on now! Rated 2 out of 5 stars
I really like the attempt... But the name is incorrect; it should be "Wannabe Vista Mail". I actually own Vista and a lot of it is minimalism, not flashy red & black colors, come on! Just look at IE 7, last time I checked, it was a soothing color blue. Black is great but when overdone it's a killer on the eyes. Also, you should change/edit some of the icons because some look like crud. Smooth out the colors, make black & grey, or gold or whatever. I'd like to have this theme as the default but in every window I find, there is some kind of messed-up detail that ruins everything (e.g. the icon you used for "attachments"). Nice try, but that's far from perfection (or at least a "7" rating from me).
