The artworks are looking really professional and polished, keep 'em coming!
Snow looks good / okay.
Obviously the walk animation is looking clunky 
Yeah you can be proud of the ballista!
Sound lines are pretty good as well.
I must admit I fast forwarded a lot because not much is happening in the game except for the art part and I’m much more of a game designer 
I wrote feedback as it came to my mind while looking at the thread / video.
Good luck and have fun in your projects everyone
EDIT: And lighting is beyond my knowledge unfortunately!
