/ic/ - Artwork/Critique

this is my drawing three years ago, spent countless hours on it, at least 20 or so files, so I assume it's definitely more than 20 hours

maybe I've gotten a bit quicker at putting down my ideas since then, and learned a bit more about human proportion, but I feel like I've had no visible improvement since then, I have made many finished work since and most were class note doodles

I can't draw people or objects realistically or recreate the design I drew at all, I only know reference and gesture conceptually, and my perspective and anatomy abilities are really limited, the creative process feels very much like me throwing shit on the wall until it looks good, and finishing work, cleaning up my sketch feels like a choir, at least when I work digitally, and it takes forever

I want to become a more efficient artist and become better at anatomy and perspective, and I've seen people recommending Vilppu's drawing manual lecture, would that help me with my goal? also is graphic tablet hand eye coordination trainable? I've seen these exercises from BaM and want to give them a try
