Thanks for working on this. The community needs a good character sheet.
What I appreciate the most is the openness of your design. The lines (instead of boxes) give it an airy, unconstrained feel. While the big horizontal divisions give a comforting sense of order. I also like how spellcasting is a supplemental page. Doing that removes a source of inadequacy for noncasters / avoids wasting space on a noncaster's sheet. And, it's clever how you put "other features" in the class & race section, and let the player figure out what goes where. Same for the generic "limited use features" section.
I know you're on 1.0, so take the following suggestions a wishlist for a 2.0, since they involve a pretty significant re-org.
My first suggestion is to figure out how to get class features and limited use abilities onto the front page, with ability scores, skills, hp, ac, and attacks. The idea being to get everything you'd need to reference in a combat onto the same page. The front page is already pleasantly full, so I'd move the soft details (weight, hair color, ideals, flaws, etc--all the stuff except name, race, class from the top section) onto the second page. Place them along other soft details like weight, coinage, lifestyle, treasure, and equipment.
The second suggestion is more design conceptual: one of the things I like about the "official" contest-winning sheet was that big central element. I like that idea, but think that the thing they put dead center--"level"--is probably one of the least-important bits of information. Instead, I'd love to see Hit Points in the dead center--that's my primary concern as a player. That, and core identity info like name, race, and class, should be dead center. If you're doing a design with a strong enter element, of course.
I've attached a jpg of mockup of such which I built in Excel.

All in all though: thanks for doing this, and keep up the good work!
