I very much like the scales you added on the arm, in addition to this overall looking really nice and clean! However, the one thing I would say is that I wished you leaned more into the Koi fish look. Like more vibrant oranges and perhaps patches of colour along the skin like the fish!

I do like the piercings on the ear, as it looks like the black dots freckled on the scales. Overall this is really great looking, could be more fishy, 9/10 - IGN

Also i like the top, it looks very unique!
