This is VERY beautifully done, but doesn't it not fit the rules for the contest?
"-must be in the form of a portrait or illustration showing a single Gnome or Goblin character with one of their inventions. The invention can be a new invention or a re-interpretation of an invention currently in the Game."
Yeah. If the official rules are to be read in a strict manner, any art that isn't directly created for this contest is an invalid entry.
Unfortunately, that gets rid of quite a few good entries, but I understand why they are enforcing it. It would essentially give a head-up to those artists already working in the field and make the contest an unequal ground.
