I added 1000 layers of various mixes of AK Aquatic Turquoise and Liquitex Titanium white. I think I got the right consistency, and most of the time I delivered the right amount of paint.
Each layer didn't seem to do a lot, at the end we can clearly see that the contrast increased from yesterday.
I'm done with the airbrush for the blue horrors for now.
After highlighting and painting the details with the brush, I might go once again.
