My client is interested in gifting that poster to their GM as a way to finish up their DnD campaign!
The poster features 4 of the players' characters and the main villain - a Dracolich, who's visuals were based on Kaladrax.
I quickly sketched all of the characters involved before beginning the work on the actual poster. The characters had rather unique descriptions, I'm a big fan of the Gypsy based Rogue character and the Wild West based Mage, I think these are really cool!
