Your artstyle is already super charming, while I don’t know exactly what your goal art style is, in my paint-over I kept the elements that I found are done well like your anatomy, line quality, and facial expressions. On the other hand I added more than I actually removed, like I said you have a great foundation. What I added is form and depth to your artwork, I think if you do want to go a more semi-realistic or soft shading approach to your style then form studies would benefit you greatly. I noticed because the original artwork is all mostly flat colors and a bit of cell shading and after reading your concerns about overdoing or underdoing your rendering, I think form and depth is really the only skills you have to work in this part of your art journey. In the paint-over I didn’t push to be fully cell-shaded nor fully rendered, I’d compare it to how manwha artists shade (if you wanna look it up) where it’s a happy medium of the two because I don’t know specifically what your going for. So the practical things I’ll list here that could help you: - form (light logic, starting with painting simple shapes such as spheres and cubes. Do a few drills to understand how light affects a simple form) - face anatomy (after doing the simple forms, move onto the face anatomy such as the Asaro head to learn more about planes) - edges (soft, firm, and hard edges. This is what gives art styles its own unique look after you have a good understanding of form) All of these can be studied on YouTube , I recommend Marco bucci
