first i wanna say that you probably made the best game i've played for years... ok, as long i can say (im not at the end at all). The landscapes are wonderful, theres much really good roleplaying stuff you can enjoy and - what is on my opionion one of the most important things of a really good rpg - there are so much details and so nice atmosphere with the weather, sound and other environmental effects, its just great!
But i've some little proposals that would be nice to be implemented - if you arent not in case to do so:
that theres the most of the landscape in snow, it would be very nice to find some footsteps of other creatures an of myself. May they can disappear after one oder two minutes, but this would be a fine detail =)
The second thing i want to suggest is that there probably are some npcs that shouldnt die (i dont have problems till now). I dont know if they could but ive lost already some npcs to dragons or icetrolls^^. May it could be done like some of my groupmembers. They just get unconscious oder sit down on the ground.
And now one big wish of me - as i said im not at the end so sorry if this is incomming (no spoiler plz!) - i would like to fly on, or transfer myself into a dragon. If this is already part of the story: I LOVE YOU!
- if not... may you can create a dlc or a mod where its allowed 
i guess im not the only one who have such an idea

hopefully to become fulfilled my wishes and with best wishes to you,
me =)
