I did a thing for a thing:

I kind of forgot what it's like to actually spend time on drawing something. It made my back hurt and I worried a lot, but it also felt really good.
...Still not great at color shading, though. Not sure if I should practice it or just focus on making my lineart show the depth and just use simple coloring, like an old Disney comic.
