Damn! Y'all pulled a great job on this track!

Theme: 9/10

This is neat racing

Ooh. I'm getting some eurodrift vibes. I like it a lot. The racing vibes are definitely there, and the arctic vibes are not hard to dig out. But like CF said, my biggest critique has to be how quiet the master is. Bump it up I beg. Additionally, experiement a big more with this track. Have fun with it

This is really slick. It reminds me a lot of waterflame's productions in terms of optimistic energy. I think it's a bit too soft in general though, and I also think when the drop comes in at 1:25 it probably would have been better to get rid of the wind sfx, since that comes in as quite a nuisance at times.
For the rest I don't have a lot to complain, other than this might be playing it a little safe; it didn't seem like a very daring/experimental track. That's just my preference in style though!

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.
