This year, I became more comfortable coloring and tried experimenting with soft shading. I know that one of the reasons why I use cell shading more often is that it's easier and faster. But next year, I want to stop being as lazy and use soft shading more often. I also became more comfortable drawing clothes and anatomy (although I'm still bad at both).
I'm still trying to figure out what my art style exactly is because I know it's there or it's starting to form, but I'm not quite sure what makes my art different from others. Maybe next year I'll know the answer.
