I wouldn't mind helping. I'll attach a creature I just randomly made so you have a visual and you can tell me what type of things you're looking for. 
https://discord.gg/nBzRQHsk introduce yourself to the group :) thank you
we're looking for things that would look more organic or mystical. one of the ideas was a large white snow-cat that appears and disappears in a puff of steam. (the steam can be made and animated using particle effects by myself). Other things include the moon, but like, personified somehow. Two Finnish witches, one good, one evil. And a bunch of creatures that just sorta look like scary amalgamations.
