Hey Lotte, you are a great artist for one so young! Keep it up!
A piece of advice: drawing from life will always help you improve. Try having a friend sit for you so you can draw them, or just sit outside and draw strangers as fast as you can as they pass. The important thing is that you are looking with your eyes and drawing what you see-- not what your head makes up (that comes later
). It's okay if these drawings aren't as good as your others, they are supposed to be for practice. Eventually you will see yourself getting better and better.
People who don't draw from life and draw from pictures or trace pictures don't evolve as artists.
