Hi Mal & Probuilder,
Thanks for the compliments. I'm preparing to post it as a review.
Quickly, I airbrushed it (Passche VL) with Polly Scale, old Pactra acrylic, and a Model Master acryl. Look closely and you can see some overspray dispite my best efforts, and several re-edgings of the colors' demarcations.
That's why some of the fine recessed lines got a bit too shallow for my wash.
