Does any one know of any good art competitions for teenagers,open in the UK?

I am 13 and have been told I am pretty good at art, I am looking to earn some extra money and thought I could enter competetions and see if I'm actually any good. I was hoping someone would know some good competetion websites or any current art competetions open to teenagers in the UK, preferably without an entry fee. Thanks!!!Does any one know of any good art competitions for teenagers,open in the UK?
