Hey, you're 13. The fact that you even have this passionate to create is something you should stick with. It's all part of the learning process. Trust me, I used a lottt of references for my artwork when I was your age haha. As long as you're not stealing anything and you're willing to make an effort to improve, that's all that matters.

Mixing doesn't make anything "semi-original". Experiment, be creative if you have to.
