It keeps a common feel through out the beginning portions, but there are some nice renditions you got going. Sure, people follow trends that will attract listeners, and that is a given. What I like most about this piece in general is the atmosphere that it creates. You stay true through the entire piece, where as you state that this should be listened to while climbing an icy mountain of the sort.
In that respect, towards the middle of your piece, you create a climax of chaos, then pick right back up to your original beat.
Job well done!
