This is something I'm noticing more and more, but sculpting sharpness and detail is improving, and it was something I wasn't sure could go a step further. My immediate impression is comparing it with Snowspeeder Luke. His likeness, the outfit, and almost every detail is a little crisper than other figures. Compared to SS Luke, the Dak figure's body isn't quite as sharp. It's small in difference, but it's there.
The headsculpts though, they're very crisp and similar. The AT-AT Commander's Jagdpur pants from Tank are really a good example of that sharper sculpting though. Very crisp, lots of detail and folding. Far superior to most any other Imperial figure's pants... it's not the newest sculpt either, but it's that trend towards a more crisp realistic look I think.
Sculpting's such a fine art I've always given leeway to Hasbro on that, especially on anything mass produced. Human likenesses especially. I'm impressed that it seems some figures are going a step further though, in terms of detailing.
