Looking good so far. I have found that when using nail varnish you have to experiment with thinning and pressure settings as no two varnishes are exactly the same. I found that the metallic varnishes tend to need more thinning than the primary colors. I have even had to go as high as 70/30 thinner to varnish to get the right consistency for airbrushing. Experimentation is the key to getting a good finish with nail polish. I also found that many light coats build up to the depth of color that you want. Good luck with the nail varnish.
