Looking pretty sweet Nino
re backglass touchups in lit sections, i usually shine a light from under the glass as im brushing the paint on. this gives me a bit of an idea how thick the paint is going on and how translucent the paint is. I did this today with my Quickdraw glass. I usually apply the paint with the light shining from underneath, then flip the glass over to see how its looking with light shining thru it...
Just a little trick that i use doing Bg touchups. Your Bg is looking great btw
