Here's the cover for an upcoming Expeditious Retreat Press Advanced Adventures module. This one was a lot of fun to do, though I was still learning my Affinity Designer tools a bit and I see all kinds of problems with it. Such is the life of an artist though, you gotta keep evolving. Cheers and happy gaming!
