I think that the beginning is quite messy with the sudden addition of instruments. I feel like the instruments that clash the most are the strings with the chiptune melody, It might be due to the mixing, but I'd suggest either making the start much quicker, or a bit slower so that there isn't such a mess there. I also don't feel like it servers as a proper entrance to the main melody at 0:24, as it sounds like if it was just a continuation of the intro rather than the main thing. I like the chanting around the 1:10, although I'd suggest the really fast instrument to be higher up and less loud, to make it sound even more icicle vibe. Knowing this is supposed to be a snowy track I can guess that it is supposed to give off that vibe, but without that knowledge, I think it would better serve if it was in an octave higher up. Overall I think that the chorus and post-chorus is the best part. It's whimsical, and there's the right amount of instruments around 2:10-2:40, I think there could be something done with the audio leveling or mastering in the main chorus to make the instruments further away and not clash as much, but I still like it. Now the part that follows at 2:47 I also think struggles from too many instruments in the same octave. Overall while I wouldn't say this is a bad track, there's definitely a lot that could be done with the correlation between each instrument, because while I believe each on their own is alright, they don't make a good mix together. In regards to the snow and race theme, I think it barely hits both for me, there's the race and chant SFX and the icicle sounds.
