The thing about art is that talent is only a small part to me. In order to be good at art, I think you just have to keep at it. Constantly draw, sketch, color, paint, basically the more you do it, the better you get. Also, never get discouraged. I experience this sometimes, and end up not drawing, which doesn’t improve my drawing abilities. However, if I get the urge, I just draw and, if needed, keep drawing the same thing over and over until it looks better to me. I make sure I keep drawing and experiment, improving as I go.
So yeah, I say if you like to draw or anything pertaining to art, never discourage yourself and practice. Also, never say your not talented or a good artist, even if you’re kidding. You’ll start to believe it and it’ll become true.
