Should i start artistic gymnastics?

Hello im 13 years old and i would love to start Artistic Gymnastics. I am 5'4 tall and I have done ballet for 8 years (I had to quite 3 years ago). At the moment i am doing trampolining, tumbling and double mini tramp but I would love to start Artistic Gymnastics!!. The club im in has Artistic gymnastics but the level I would be at has like 10 year olds in it. I want to do competitive gymnastics too, what should I do?? Should I move Gyms (my mum said yes if you want to move gyms to be with more people your age) I have been at this Gymnastics Club for about 6 months. I can do: All splits, backbend kickover, front sault on tramp and kinda on floor, cartwheel, round-off, handstand, and im working on other stuff aswell :). Whats your opinion? Please help :) I dont know what to do. Thanks for reading
