Wow I only started when I was like 12 years old....

Your age doesn't really matter however you might not want to mention it as some people might dislike the fact that you are young.

It is really about what you can contribute(Levels graphicss gani ect.)
If your work is top of the line yiu should be able to get hired anywhere.

However GP positions you should forget as they will reject you as soon as they figure out your age
