anything you do in art is all a learning experience. when i first learned to draw when i was young i use to trace, because it helped me get used to lines and curves and shading, it taught me alot, mostly cuz i never took lessons, and that was my way of learning. the best advice i can give a fellow artist is, KEEP practicing, keep painting, keep drawing, and remember you can always start over, and you can always erase pencil.
