I have used a 70,000 poly model in my module without too many problems: I had to split it up into 8k poly chunks to get the game to load it, but it didn't perform too bad. That said, there was only one of it, and it made up almost the entire area.
I'd be more worried that the art style will look totally out of place, personally. Nice work though.
Edit: apparently I underestimated my model's polycount : p
