How about something like this? I've put in a Powers/Abilities section too incase anyone has a cool idea beyond the list we already have (or their character embodies an emotion not on that list). It's not a particularly long CS, but personally I feel less is more when it comes to character sheets - If it only has the basic information down, it gives a lot more room for character development later on. If you have a detailed CS, people feel more inclined to write their entire life story in it and have relatively little character development in the IC.
Leaving the underscores in will prevent Iwaku's formatting from screwing up. Just delete them once you're done filling it in.
