I like the liveries, especially the arrangement of the patterns and colours for each hololive member, they do match with the car. I was hoping that the liveries would be allocated to one car per generation, but that's ok. Only thing missing are the members' avatars and maybe some artwork, specifically on the doors and hoods/bonnets of the cars. But an excellent job all round. Good job!
And a few things to note:
These car liveries are meant to be lowkey. That meant not making it a full itasha because there's the problem of finding the best artwork and where would be the best placed to put it without making it cluttered. And making the designs as simple as possible meant a consistent delivery of what the design implies.
