It was a really nice read for me ! 
Meeting Harrow and walking with her to the Hawkins residence was good ; even though as a reader we don’t know her she still felt like a friend, the way you wrote her and MC’s dialogue was fluid, and we got more informations about people and stuff without it feel unnatural. Even if we walked through the snow it felt warm. 
Made me forgot why we were even going to the Hawkins in the first place. 
I don’t know how to put it into words but the various transitions from a light-hearted moment or a memory, to the present day ; the war and the people lost from it, I think you nailed it. 
Oh and I also really liked the small focus on what kind of humor MC’s can have, I think I never saw that before ? But it’s a really nice way to add some subtle flavor to the texts. The accidental slapstick one is so cute, my favourite ! 
English isn’t my native language but when we meet Mr. Hawkins I think he should have said “He was” instead of were, when he was talking about his son. Unless it’s an old term for the time-setting ? 
I wish I could gave you advices and stuff but I don’t know anything about writting, so I’m just gushing over your work.
Good luck with your project, author !
