1. The map.
Clearly show the roads and tracks. Yes, snow is nice and may be 'atmosphere', but atmosphere counts little if you are frustrated from trying to find the path to the next town or village you haven't been to yet. I'm all for exploring, but I'd rather explore rather than groping my way in circles looking for a track.
2. Horses.
I've given up on them. The lack of mounted combat is a big drawback. Having to jump off the horse, ready weapons, then turn and fight the wolf nibbling my horse's heals is annoying, same same for trying to speak to someone. Further, the lack of being able to mount companions is a drawback as well.
3. Companions.
So far, my companions have: Pushed me off a cliff after I rode up on an outcrop to look at the view, and Lydia ran into the rear of my horse; Got in the way of dual-wield sword attacks numerous times, after we started the combat with her behind me; Killed me twice by shooting the opponent I was attacking with my sword; Got lost more times than I care to remember. Not to mention being so close behind me that 3rd person view was useless.
4. 3rd Person View.
Try shooting arrows at a dragon overhead when you are standing in a field of wildflowers. 1st person view is almost pointless because the dragons move so fast that they are out of your tunnel vision too fast to make it worthwhile, and 3rd person view with wildflowers etc is even worse.
5. Signposts.
When the light hits them a particular way, they are almost unreadable. Surely the locals would realise this and darken them somehow.
Good game though, very speccy.
