Enviroment artist, looking to help out,

I could use a map builder, I’m working on a game with 35+ maps. It’s stylized art style.

Obviously this would take quite some time myself, more help the merrier.
This is a game that will be released commercially so you’ll have to give me the permissions to use the maps, and I’ll give you payback for a period of time if all goes well.

Tl;DR: make 10 stylized maps, get paid if game sells well.
