These are definitely an improvement over the current icons but while some of the design rules are evident, i think a bit of refining is in order.
The games and download folders both need a complete redesign as the ignore the design rules that the other folders use, and why are the symbols on each folder white except for the Mac folder?
I have fond memories of the Internet 20-25 years ago.
How did it turn into this much of a mess? Social Media, SEO, adverts, data mining, profiling, privacy nightmares... what a shit show.
