We got a group on slacks for marketplace creators on Roll20, and we have a new channel for a "monster of the month", the first one was "Coffee Monster" and this is what i did.

If you are interested I have made several sets for Roll20 with a pixel style, you can find them here https://marketplace.roll20.net/browse/search?keywords=&sortby=popular&type=all&genre=all&author=Dsurion
