I wanted to make something similar to one of my earlier pieces to see how much I had improved. I got it to state where I felt it was almost ready and needed just a bit of cleaning up, but that cleaning up felt super tedious and I kinda abandoned this thing for a long time (years or something).
Few weeks ago I felt like drawing something and opened this thing again. Instead of finishing the cleaning up, I just redrew huge parts of the image. New stuff was much better, and didn't need nearly as much cleaning up.
