Quite well done. I think with your style and talent, you could make a lot of money. I can really see a lot of people wanting you to do art for their products.
I bet, however, that you could do better than commercial artwork. These are really good, much better than I could do, but I think soon, if you keep up with it, you'll become even better and possibly become a professional.
Aw, I think that's the nicest thing anyone's ever said to me! Thank you so much. I've had very little formal art training, so I am hoping to improve a lot in the next couple years when I will be taking art classes.
