I'd say that was a rather successful experiment! And a good tip or two about winter scenes: Make one or two fire bins out of oil drums for the workmen to keep themselves warm, plus trim some very old tinsel down to the base, with a little bit still there. I know Calebtrain did something like that in his Christmas vids.
Yes I did try this on my own layout, which you can see on my Model Railway Layout in winter snow video, which I do have to say to does take a lot of time clearing away especially if the plastic stuff lands on bushes, which I had to hold down the bushes with my hands and carefully use the vacuum to clear the snow up, and believe me it wasn’t all that easy 😅
