I love how it looks! the Yellowjacket pattern to determine the tunguska, that are not red nor bakunin white-orange...
I’ve got something similar going on for my Nomads. Red/yellow/black/off-white ties the whole thing together, with Bakunin units getting more of the white, Corregidor more of the yellow and Tunguska more of the black.
I have started to paint all the Tunguska Models yellow and all the bakunin green a while ago. Found that really fitting to distiguish them. Yours look pretty sweet! Especially since you do them all in yellow.
