You look really young (I'm assuming you're not older than 19 or 20 at the oldest). But for real, you dont look bad at all. You have kind of a sweet "teddy bear" type face that girls go for. You know...."nice guy." You look like you probably have a really nice smile too.
Even supermodels sometimes wish they looked better, man. lol. Don't worry about it too much. Just focus on being healthy and the rest will follow. That's what I do. I focus on outliving these "pretty people". Haha ;D
