Am I good enough be a professional and start selling art? (13)?

Here is my drawing I just finished of Dylan O Brien. I'm 13 years old and self taught. How can I become professional? Anythink I should Improve? Do you think I can sell stuff? I need to raise money for better art supplys since the one above was drawn with only a regular pencil. Also, how can I get celebertys to notice my drawings? Thanks for answering in advance!

If there is a tail of film sticking out of the canister, there's a good chance that the film has not been used and is therefore not exposed. If the film is not sticking out, the film has probably been exposed. However, you can't tell if the exposures were good until you develop the film. There's no way to tell just by looking at the can. If your curiosity outweighs your frugality, have them all developed.
