Being that I got an airbrush for Christmas, I thought I'd try it out on some older, cheaply-acquired models. All-in-all, very happy for my first run.
The primed model. I used Vallejo Black Polyurethane Primer.
The color gradients. I will probably add a final edge highlight, but I am not sure yet.
I went over these with some P3 Turquoise Ink, thinned about 8:1. I really like the effect (whites and greys are hard to get done right with an airbrush, though).
