Voice Acting for a young Character

Hey everyone,

my name is Max and I am 15 years old. Now before you stop reading because of my age, I would really like to have a go at voice acting. I've got quite a deep voice, but I sound nothing like an average Character in Morrowind, but I'd like to maybe try a young Imperial. Would you have any suggestions?

PS: I've got a british accent, which may or may not come in helpfull.
