One of my favorite artists, only thing is his 4k stuff are bloated in terms of bitrate IMO, so I end up compressing most of his works. Oddly enough this guy's stuff are by far the most compressible of any artist that I have come across and I don't understand why. By that I mean the quality of the compressed vs original are indistinguishable to me on my 2k monitor.
That being said, here's the 30FPS kiriko ones posted above in case anyone wanted it as well.
Changes:
4k-->2k
~65k bitrate --> ~12k bitrate
~300 MB --> ~60 MB
