Thank you all for your comments.
@cowmeat, thank you for your time that you've spended on writing your post.
I agree with you that it sounds overfilled and sometimes it sounds chaotic.
Well, as a some kind of protection can say that it must be chaotic because the main theme of our single is burning Prospero, the home of Magnus who singing it (me). His brother and his father have betrayed him. He lost his legion, his home, his creation and so he lost his mind. He turned into a chaos that's why it seems messy from time to time.
I can't say a lot about an instrumental part of it because I'm a bit far from it.
Must say that we've been hurrying because we've had a challenge with one guy that we can release a single with a feature and with a lyric video in month. We've lost it because I've got micro etc. only at 10th day since our challenge and then a guy who've been singing a feature part was like "Oh sorry I'm ill I'll sing my part... Idk when but I'll do sry sry sry" and then we had troubles with our videomaker etc etc etc.
It's our first try to teamwork as well. We have problems and we will work to fix them for sure. Thank you again for your criticism and sry if I wrote something unable to read I'm still not pretty good in english.
