Beautiful in all!
Working also with snow atm. It is harder than i thought to work on, to get half way realistic results.
After tweaking like hell some shaders over another ones, combining everything i found for free in the forums, i ended up depressed with very simple settings at one up to max. 2 shader again, with close to 0 subscatter like FX. But i´m using much wider scenes/landscapes, so no shiny closer up optics are needed now - pheew...

I like the grade of "thickness"!? of your snow.
