I tried this mod some days ago because it sounded great and it had "Darknut?s" in the title ;D
Installed it, started the game, and it worked...but how... O.o
It kind of feels like it SHOULD feel more natural, but to me it doesnt.
Maybe its because the screen is "shaking" so much, especially when running, according to the body movement you can see in 3rd person. After a while that "shaking" made my eyes hurt and get wet...made me think of myself running in real life, and I think my view wouldnt "shake" as much...
The different position of the weapon in my hand also looked okay, but running with shield and weapon in hands was so "nervous" with weapon and shield "shaking" all over the screen...made me crazy.
I tried playing with it for an hour or two, but then I switched back to normal and was happy again.
Had no "technical" trouble with this, so I guess its well done, just not for me.
