If YOU love drawing...then I think you should keep drawing. :)

I think your a good artist. You just need more practice. When I started out I was terrible. I only knew how to draw stickmen. But I didn't give up. I kept drawing and drawing without lessons. Then eventually I found a style. and I kept drawing in that style. I'm still not the best artist in the world. but I keep drawing...keep posting.. thinking hopefully that someone will like it. Now I think some of your work is cute. And I think you have potential. Just keep drawing. Find out what suits you. And also find out if you like drawing on paper or digital paint. I can't really draw well on art computer apps but I can draw better on paper.
All I want to say is keep trying. Explore! I think you have a lot of great ideas. Just keep drawing. I promise! If this is what you like to do...don't give up!
