All Bowser, but he looks like Peach...an edgy Peach lol
Great job, I like how smooth the design is, but the sharp areas are selectively present which communicates a core difference between Bowsette and Peach. Superb coloring, I like how you handled the shadows, especially in the hair and horns.
It took me a moment to realize Bowsette has strands of hair sticking out that are line-less. For me personally the darker colors having that line-less look are great, but the brighter colors, not so much. Not sure if it's because of how bright the yellow is, or if it's because the background doesn't contrast with those line-less yellow strands as much. But the yellow strand gaainst the horn and its shadows is fine, so I do think it's a matter of what colors are against it along with my own personal taste.
