I noticed the official character sheet uses a black background where the characteristic scores are circled, but the sheet in the back of the book uses a white background. I personally like the white background better. With the black background, it is hard to see those circles.

I suppose I could just make photocopies from the book, but it sure would be nicer to have an official character sheet with a white background for those scores

Nice catch. I downloaded the character sheet but didn't look at it, assuming that it would be exactly the same as the one in the rulebook. I'd like to see an official one that looks like the rulebook's as well.
