I'm glad you enjoyed it so much! Drums are definitely a struggle for me when composing. I've been trying to improve some of my drum fills but i'll continue working harder on that.
The majority of the track is in 4/4 with different bpms and slightly different phrasing / emphasis on different beats. The second part is in 5/4 an briefly changes to 6/8. I didn't want to go too crazy with time signatures like I normally do so I could keep myself more focused on atmosphere. Though 5/4 is 100% my favourite time signature to compose in.
