I've never seen these models before -- does anyone else think those eyeless shark-men look like cool riding beasts? Or am I just weird?
Everblight seems to be all about pale, so I would say pick a pale color that you like -- white, light blue, sickly purply pink and then find an ink that matches up good with that base color. Paint the whole thing in the base tone (over a white primer), and then wash the living daylights out of that sucker. Then, if you are feeling up to it, go back and paint the base color back onto stuff like the top of the head and the shoulders and anything else that would be lit by a light coming from above. Paint the teeth white and possibly put a contrasting color on some of the armor detail -- bang. Shouldn't take more than an hour (and probably a lot less).
