If Zan's eyes are supposed to be red, with him having black sclera, I would suggest making that more distinct, because said eyes look the same as his fur color.

I would like to suggest making it so that it slightly hails in the forest when it rains, because Lairen shouldn't be cold with the fur that he has, unless the temperature severely drops, he is covered in fur, after all, and from his patterns I want to assume that he's a husky, since he's a dog not a wolf, and their fur is generally thick enough to protect them from the cold unless they haven't grown in their winter coat. That way, the fireside scene feels like it is playing up the fact that he's not prepared for a sudden change in temperature, and that the seasons are changing.
