i'd say about 16, but then I'm pretty generous. I'm your age and I have red hair too. Something about the red hair and freckles seems to imply youth, which can be discouraging.
It's not so much about how you look as it is how you act and talk, however. To prove it, I've had 2 near-strangers say I looked 13 (scary!) and then people who knew me better guessed I was in my twenties (oldest guess was 25).
Just let your maturity show by the way you present yourself and don't wish for old age too soon :) Maturity is what you want, not wrinkles! :D
I feel your pain, and you're not the only one! Just want to say keep your chin up looking young is something time will fix whether you want it to or not...:)
To me you look 14-15. I think it's the young red head you know? Something about long red hair seems childish to me. But is looking younger than you are a bad thing? Think of what you will look like when your in your 30's. Maybe your 20's! Not a bad thing in my opinion :D
Yeh you look a bit younger, I always get people saying I don't look 19 and it really annoyed me when I was in school that peeps thought I looked younger but I like it now lol-i just think I'm gonna look younger when I'm older and everyone else will look old so it's all good! haha.
