The potential prize makes this interesting, but the contest doesn't seem to be oriented on originality and creativity, it seems that right now it's a concept art contest.
What is the applicability of a game developer that is designing an engine? Say, for example, I use my RPG engine with some modifications to fit their breeding and racing requirements. That wouldn't be very hard to do. But, the contest seems to be focusing on the design details and not the technical ones. I have no interest in competing in design popularity contests, I'd just want to make a game that fit the criteria. Anyone can make Poser models look like game models but making a functioning game is a different matter altogether.
Come see the WIP!
