Yes, it won't be the 1st time in which I hear that if I haven't got anything nice to say, I shouldn't say anything, but trust me, if I lived by that, I wouldn't be hated by everyone.
Honestly I find it difficult to find something nice that I could sugarcoat my comment with, because the single good moment in this video was the scene at 0:44. This song is not an easy one, but it's still not a track that you can just fill like a plastic trash bag, and I say that because what I think I saw in this video were dynamic scenes that sync with nothing, flow with nothing, and mean nothing, and get to nowhere. I also want to say that the colors are disturbing, but I'll shove that in the subjective drawer.
I'd give suggestions, but what I believe is that you're on a level much better than this video, and what you need is to try. Not suggestions from this hater.
