I really don't want to mention this... But how the camera looks away from where you are pointing. It feels so strange, and I just couldn't get over it. It should be the other way around. When you move the mouse to the left, the camera should also move to the left. It makes no sense, that you are focusing on an object to the left (moving your cursor there), but then you see less of if, than if you move your cursor to the right.
Okay, now that I mentioned it, just want to say that everything except this is lovely. (Although not happy)
Edit: I just didn't want to repeat what everyone have said before me, and that is why I kept it so short. :)
