Done this recently, a drawing inspired by the works of H.P. Lovecraft and the boardgame Arkham Horror. Not sure, if this qualifies the picture as FanArt, as Lovecrafts stories and ideas are pretty openly available anyway :) But if it does, sorry! Anyway, the picture shows a small group of people trying to seal a gate to another dimension (or maybe to R'lyeh), but first, they have to get rid of a Nightgaunt, which has emerged from the gate. Technique is pencil.
