You'll gain experience, you're only young yet.

Don't worry about not taking it at GCSE. I did but it isn't what helped me to get better. I'm still almost entirely self taught. I also did A-level and thats where I realised that art education wasn't for me. They wanted the abstract stuff which I don't like. I wanted to do realism. I didn't go beyond A-level.

I see you are in Lancashire. I'm in Yorkshire, lol. We have similar accents, haha...thats if you speak broad. Still, one of my most inspirational artists lives in Lancashire. His name is Steven townsend. Google him and take a look at his stuff. You really can't tell a lot of it from photos. You always need your inspirations in order to get better.
