Hi Muhammadreza - welcome back. I like this piece a lot. I just watched the miniseries last night. a very powerful series. For me, you captured the essence of what Pripyat's forest might fee like now. I might suggest, you approach the drums with an orchestral feel, or like Ringo did in some of the Beatles later pieces, He played mostly fills, and turn arounds. The sparser drumming leaves more room for other instruments to shine..
I think this piece is my favorite of your work. Good job.
