That's a nice interesting perspective that not many use as matter of fact. Looks pretty good.

The lineless art sometimes confuse me due to, well, the slight change of tones to make a character's body parts, I guess that is why when there are too many characters in a pic, the colours must be well used, and even use palettes that looks unnatural.
...I say this because that green-mint colour surprised me. Still looks nice though.

It's entirely possible that that was my line of thinking. It's... also possible that I just like giving characters outlandish colors for some reason.

Hah! The colours are okay, is not like they are too weird, seeing around here (FA) OCs that are pretty colorful and me liking MLP colorful characters are very common, is just that I thought that with lineless art like yours, having a couple of characters with similar palette would be hard to work with.
