Shoot a roll first, indoors, preferably in the same environment. Develop, print, and see if it matches your expectations. It certainly has a look and character, but it's not in the same league as BW400CN. As 2F/2F and Tim suggest, downrating is definitely advisable. Consider a strobe or other auxilliary lighting, otherwise be prepared (and prepare your model) for artsy, grainy dreck. Please forgive my post if that is what you are going for.
