Repainted my old 2022 piece.
Painting in black & white helped me a lot with noticing tonal mistakes, and it was easier to work on details since I wasn't overwhelmed by the colors (apparently I can't even handle monochrome, ha).
Funny how, a few years ago, I would hate painting in black and white and then coloring it. But now do almost everything like this or with B&W filter on top of the colored artwork.
