[MENTION=67]Rune[/MENTION] Interesting design! While I appreciate the minimalism...the real litmus test for a one-page character sheet is not a 1st-level PC (who it is easy to fit onto one page), but an 11th-level PC that has been "lived in."
I also second the value of including portrait space – one of the most fun I had was ad-libbing D&D where we began with character sketches and then rotated them around the table, each player adding an artistic touch like a pseudodragon familiar or a word or something to each player's sheet. It really did wonders for kickstarting everyone's creativity.
