Kim from
xenique I would say has done some amazing styles more notably the imagery she designs which compliments each and every design she outputs. One of a few people I consider a designer since she from scratch designs her own imagery and integrates them into the excellent styles she provides.
Forsaken is another, I don't think I've seen anyone else implement colour usage as good as this guy who has a very good eye on structure, colour implementation, font usage whilst keeping a clean uncluttered minimalistic look. His imperial style is a style i'm a fan off but even more so the colours and navbar enhancements he makes.
I can't seem to find a link to the imperial style screenshot but i know he's posted it here since I'm sure it's not yet released.
