Color palette and one layer challenge!

As my bestie described them:
Lovely looks sweet but she can’t beat you if she wants.
Colorful is super unique and proud to be himself.
Midnight is a daydreamer and a quiet boy.
Emerald is literally so h ot, and he knows it.

This was just a challenge and these aren’t anything special but I really enjoyed drawing them! They remind be of Japanese oni or yōkai. Pretty neat. I love their colors, but they don’t quite match up.
I really enjoyed doing this, especially since I’ve been out of it for awhile.
