From 3 to 4 stars, the new 1.3v Day time is really good, i like it.. i think you'll still changing and tweaking the pp_filter until you get the "Perfect" effect but anyway this 1.3v is good for a backup until the finish version release. Keep the good work!
I'm thinking the filters reached a sweet spot, not much to change there, but I'm thinking moving into some Time of day weather settings, making it easier to jump into a race without having to switch the filter
2nd and 5th picture are really good, the other one i dont like it to much to be honest, but keep the good work you can make a good filter from that, i like the idea of GTSport copy because GT S have a really good lighting system.
