nice try on such a challenging song to map
You can practice handling note density and establishing rhythm using songs that have drums
Tip: Try searching for drum patterns online then applying it to your notes
try using handbrake to lower the file size of the video
for some editors will freeze whenever it opens a file with a video too large in file size
Overall, I think you should work on the note density. There are WAY too many straight 1/2 notes that I feel like you can shorten. Also, I would say to have a reasoning between don and kat. At the moment, in the 1/2 patterns, it seems extremely random. Try to improvise and see what you can specifically do to make it more unique and not just 1/2 patterns.
If you're a newer mapper, I suggest reading this. https://docs.google.com/document/d/10Ws4BnmUpsiMs_xm5V37qtk6RDa6SimgwDVFMUaUbR4/edit?usp=sharing
Extremely helpful, and I think you got this :)
