Hew is an NPC from a tomb of Annihilation who is missing an arm. I found the model on thingiverse (unfortunately it’s been removed), printed it on my resin printer, clipped an arm off and painted it.
I've always had a lot of respect for people who paint as a hobby. I know I don't have the patience or skill to do art, so I'm always flabbergasted by what people can make. Great work, and thanks for posting it here!
