Am I too skinny to compete?

[kahbenator]

Hello, I'm thinking about competing in a natural men's physique show. I'm 19 years old and this would be my first bodybuilding competition. I'm about 5'9 and about 150lbs at 12-13% bodyfat. I think I look pretty good, but do I lack the size? Not that I have any expectations of winning, I just want to do it to see if I like the suffering and the challange of it. What do you think, should I pull through with it?
