I used to spend a lot of time making detailed and clean lineart, but at some point I started skipping that stage and going from the rough sketch straight into the painting phase. For me, clean linework just felt too tedious to create. When I do make lineart, I usually do the coloring on a separate layer, and then eventually merge the color and lineart layer, which allows me to paint over the lineart in some parts and really blend it into the coloring.
