100% agree on your points Frank, and I think he definitely needs a much sterner look.
Part of the trouble looking at pictures vs the sculpt is the angle presented. You so rarely ever see Bullock looking straight ahead at you with forehead and chin in line - he tilts his head forward (chin down) and this changes how his entire face looks. It immediately gives him a more aggressive look but that's not how the sculpt WIP is presented so it's harder to judge.
His mouth could probably have the lips pursed together more (rather than relaxed).
Hard to comment on the eyes until the eyebrows are in place, but you're probably right about needing to be slightly more squinted. They may also need to be slightly deeper set (hard to tell from the rendering).
Not sure about the forehead / brow / cheekbones... Something looks off but I can't quite place it. I think his upper cheekbones are definitely too wide and it's creating a slope from his forehead down to his cheekbone and that's making his eyes and brow look wrong.
I think the final touches will be critical - the wrinkles etc to make his face look like it's under tension.
I don't know - all I can really say is that he needs more kinetic potential. He needs to look wound up and that means he's tense in every facial muscle. I think Will is definitely on track, but it's hard to say until more detail is added (which makes it harder to make changes down the line I know).
