One difference I could spot was the shading, it seems lighter in the right pic, I’m not sure if I’m missing anything else though

Anyways, good job, I’ll look forward to more :^]

I’ve been noticing that certain details on the sprites look like they were meant to be hue-shifted, but weren’t because of the color limitations. Like I’m working on 092 right now, and he has a dark red accent near his eyes, but if I hue shift that towards purple, it matches his main color better. Or for 091, his main shading color was used for shading on his teeth, and when I hue shifted it towards blue, it matched the greys of his teeth better. I don’t know if this is just good sprite work or if I’m just way too used to hue shifting…
