I like this and the art you used is really good too. I am having a little bit of a hard time understanding the interpretation of having these heavy guitars and stuff with the art given, but that sounds like a me problem lol.
I really enjoy the softer parts and there are a lot of neat ideas in here that make me go, "oooo," or remind me of things I've done myself. Love the introduction of violin/bowed strings here and is that a flute near the beginning? Making the strings sound like a synth with a gate on it is an awesome idea!
My critique would be the guitar panned on the right that comes in at 2:18 feels like it's "outside" of the mix. Maybe it just needs some more reverb?
I also am just having trouble relating this to the art. It does relate! Like I'm not saying it doesn't, what I mean is like, I feel like you are telling a story here that is more intricate than what I'm seeing on the surface here, but I just don't get it.
