Emoji Character Design Challenge

A little character design exercise I did over on tumblr.
Folks would send me three emojis and I would try to craft a character from them.

I don't really know how to describe this guy. They're like a... fire spirit maybe?
Idk, I just thought it was cool to make their hair a portal.

An angel made of hands. Very heavily influenced by nn-ee-zz's art.

Little Snow Catgirl. I'd like to actually use her design for something because she's kinda cute.

Okay, here me out.
She's a sea angel, like those cute little slug you might have seen in animal crossing.
They're predators! And the part that gives them color is their digestive track! So it gave me an idea of making a freaky monster girl.
