Well, as to the picture, the subject's expression is unfriendly. Other than that, maybe you mean the tonal qualities? The lighting is extremely flat and frontal, no modeling, so there's no roundness or dimensionality to the subject. Should I see something else that the film can be blamed for? 🙂
I believe Kodak is offering three C41 B&W films. There's T400CN that has no orange mask (so I've been told), there's Portra 400BW, and finally Kodak Black & White 400 Plus which may be what you have. I think the latter two both have the orange mask and are intended for machine printing on color paper.
I've used Agfa Vario-XL, discontinued long ago, and Ilford XP1 and XP2 Super, none of which have an orange mask, so are easier in the home darkroom on B&W paper. I bought a few rolls of Kodak T400CN to try, but haven't yet so I don't know what it's like. I'm very fond of the Ilford XP film.
