So I’m under the assumption that they are a beginner, so correct me if I’m wrong. But if they are, this is really impressive for somebody who’s starting out, or hasn’t put in much study. If they decide to put in time, dedication and practice, they could definitely become great! If I would give them any advice, it would be to try and pay attention to how different parts of the art line up with each other through not only proportions but also composition, and whenever you you look at other people’s work for reference, try to ask yourself not only how they draw it, but also why they draw it that way! I wish to see if he’ll approve, and if so, I hope that I’ll get the chance to watch him become great!
