Well, obviously I'd want to be male; that kind of goes without saying.
I would want a little bit paler skin (even though my skin is already really pale), and not have any freckles. I'd want to have some muscles, like a six-pack

, but I wouldn't want to be too bulky or muscular. I would want to be about 5'11" tall, and be built so that I could move quickly. I'd want to have my same color hair (
very dark brown) or black hair, and I would want my eyebrows to be a bit darker. I would want my eyes to be either green or blue (they're hazel now - mostly green). I would want a somewhat pointed nose, and a sharper chin (not so round).
That's about it. I used the phrase 'I would want' too much, but I'm too tired right now to come up with a better way to phrase it. I don't really have a celebrity I'd want to look like. This was fun!
