I really like the SFX's at the beginning. The intro really sounds like an intro to the race. The countdown voice doesn't fit in my opinion the rest of the instruments, as it sounds much more like a countdown to a fighting game than a racing one, and I'd suggest using one with a lighter tone instead. I think the hit hat's in the drums should be toned down in volume, as they are over present. The overall instrumentation is very nice, and get's you pumped for a race in the chilly environment, truly makes it feel like a complete narrative. I also really like the guitar melody at 1:28, the chords are amazing there, and the key change also works greatly. My only complaint is that I think the song is a bit too short, as the intro and outro combined feel as long as the rest of the song. Last thing is that I think what I think would be the strings before 0:48 sound like they should be more quiet, there's just way too much going on in that section.
