It's a good start!
Are you targeting a specific film stock to emulate? It seems like you're aiming for negative film now since you're talking about wide DR. Positive film actually has a lot more limited DR, generally speaking. The color images, while nice, don't really "feel" like any film stocks that I know which seems a little more digital.
The black and white images, for me, feel like something shot on a modern t-grain film (T-Max, in particular). I think that's a combination of the sharpness of the image, the contrast applied, and the very fine grain. I probably wouldn't think of it if not paying close attention, though!
