That's a bit complicated since we don't know how you look like !
But... I guess, you'll have to start by saying if you're a boy or a girl, for exemple I am a 14 year old (no s because of the preposition "a") boy who has short brown hair and who's quite tanned. I'm not very tall and i have green eyes.
Is it a physical description or a description of you personality an tastes ?
I'm fond of playing tennis and i plays the guitare. I'm very good in Maths and terrible at Biology...
Sorry, i hope that was a little helpful ! :) Good luck!
