http://www.lookshy.dk/sheets/ - Great character sheets for all 2e exalted types, working on DotFA too!
http://www.bazzalisk.org/ - Some of my personal favorite character sheets, I actually prefer the old style due to my dislike for charm cards though. Still great stuff, not just character sheets.
http://www.voidstate.com/rpg/ - Not sure I can say enough about voidstate, I think everyone pioneered the advanced character sheets off his design. Not to mention all the great other goodies on his site, great exalted name generator!
http://www.alabrax.com/exalted/content/character_sheets.html - Big list of character sheets from single page to multipage, certainly contains some other goodies on his page as well.
