This chart is very overlayered, I think it's "forced difficulty" and I think it would be a better chart if it was easier (less dense chordstream). But I know that if you want to rank a hard map, you need to make very high density. So I think it is okay, because patterns are very consistent.
You can consider nerfing some very dense sections though :)
