Well, the whole idea of this challenge is to simulate the kind of work I get at my job... and that limits it to structural stuff. If characters were to be one of the choices, the challengers would need to be able to get at least 2 done, as that's the amount of time in a month I would be able to get a character done.

Of course, I realize that I'm talking a 9am-7pm (at least) job time, here. If you guys want, we can just ignore any sort of time restrictions my job gives me and just worry about it being within the month of September.


EDIT:
Fairness comes into play, though, as someone who chooses an environmental concept provided is going to have a heck of a lot more stuff to do than a character concept would give. Afterall, an environment concept's poly limit would be closer to 50,000 triangles... a character would be 3000.
