These are all outstanding!
I was looking at the camo Ukraine Viper and was thinking what if Ukraine received F-16s from storage and painted camo right over the standard USAF scheme? Leave the gunship grey and add the two blue colors as an expedient way to make them look different from US aircraft. Just my $0.02 worth.
Also the four color Viper from Georgia is a real eye catcher!
Any way you could list the colors you use?
