I really liked your video, I felt like it really knew what it was doing and never got over the top or off with the synch. The beat is never missed until the end, well, that also became a weaker point as the video never exactly surprised me with it but it didn't really bother me and it's a very good thing in a collab, it's quite impressive to have an homogeneous pace like this. That being said, I would have loved seeing a bit more impacts like the one at 1:50, really cool!
It has some very nice compositions, subtle but helping to set the mood and clean. I really enjoyed the ink-like smoke. To be fair, the monochromatic tone helped a lot with that and I am not a big fan of all-black-and-white cc. I got the concept right but I still think it could have been done with a tad more effort, like maybe still keeping some elements in color or making a more detailed way of desaturating things... But I understand and respect the choice.
Overall it's a very solid video and, just in my personal opinion, it had everything it takes to get in the top 10/close to top 5. Good job to both of you!
