Your composition skills are evidently strong: the way you made the instrument groove is great and kudos for the odd signatures! I particularly love the bassoon and contrabass parts, they’re so realistic and playful. I’m less convinced on the other sounds exacty because they’re a little in contrast with the realism of those, but again, you show to be a great composer.
The atmosphere is great as well but it doesn’t give me necessarily arctic vibes that much to be honest, so correlation to the theme might be the only real weak point of the project
Solid work, all considered :)
