>>48350165I don't know all the themes you're going for, these are just my first impressions. I'll point out some of the changes I'd make, but some of the ones I circled I wouldn't know what to do with. They just need more work imo.
1: It's face could be a different color. I think the monotone colors are fine otherwise.
2: Maybe the markings on it's torso could have 3 different colors? Doesn't need to be symmetrical. I don't know the exact theme here. Tips of the ears could have a different color like muh pikachu. Maybe matching the torso colors and not symmetrical in colors.
3: Skull and detail on the legs should just be more white, nothing else to say.
4: The stripes could be a different color. It just looks like a wasted detail otherwise. Could just be a different shade of the original color if you want.
5: The swirls on the brain could be a different color. The body/tentacles are already bland, so maybe the brain stand out for a focus/point of interest.
6: Seems like this line getting more colorful is the idea? I still think the first form should get another color. Maybe the entire line for have brighter and yellow eyes to make them stand out?
Not every design needs (x) amount of colors, but these are just the ones I think needed tweaks.
