Very cool icons... but maybe look for a matching skin...try the IF skin zone http://invisionfree.com/forums/ifskinzone/ they have free skins with free CCS or CSS codes w/e you want to call them.
Eh, they look a lil tacky as well, a lil childish to me but meh, its a diff look to look at but it makes it load slower as well like 2 sec slower lolz
