I want you to take it farther
It's amazing to find you so gifted at such a young age. However, I want you to push your skills to their limits. I noticed that you haven't drawn animals yet, so start drawing them. Also try to put multiple people into one work. Learn how to make backgrounds too. The only way you're ever going to get strong is if you are determined to do what you think is 'too hard'. That's not only true in art, but everything else.
