I've recently submitted 2 spritesheets of the fans for both WLK and TMK, and they are still pending.
Are you going to update the spritesheet since all the official names are nevealed?

Yeah, but aside from Salsa and Flare they're low-color versions of Katach's full-color sprites (so it probably won't be uploaded here unless Katach & I collaborate on a spritesheet of both the full and low color versions)

My version of the spritesheet is still pending. Have you made the Rolling LIVE cousins in the 8-Bit style yet?

I didn't expect this to happen already. I'm impressed, actually, because these are quite good!

I think Marcy has 5 colors, the only one with 6 colors is Hans, I think. I also have full color versions for the other couins below the classic style which removes the color limitations so you can have as many colors and as much detail as you like; the full color versions of the original cousins are already made by Katach314, the others, I included with the others. I have both versions because there will be an option for Classic and Gorgeous mode for Katamari Damacy-Sama, the potential third sequel to Katamari Damacy-Kun. I also have death sprites which are based on the front facing ones so every cousin has an actual death sprite instead of just the walking sprite flipped upside down. I color-coded the specific boxes to correspond who gets credited. You can use my sprites, just make sure to color the boxes so you can credit.

Thanks!
• I did see your sprites first, but I tried my best to avoid copying yours (though for Clay I didn't really have much of a choice considering their design).
• For the color limitations, I try to aim for 5 colors max, but if I absolutely NEED to go up to 6 I'm willing to do so. (since iirc Marcy uses six colors)
• I probably could've removed Charlie's head stripes, Shabo's prickly spots and the pattern on Fukutsuchi's head, but their sprites felt empty without 'em. I'll probably add alternate "simple" versions if/when I update the sheet after OUAK's launch.

This looks really good! I wonder if you also took inspiration from my sprites. For me, I try to limit the number of colors per sprite to 4 colors maximum and have low detail since that's what the other cousins have.
