Another Kill Team...
"Decent" is a hell of an understatement there.
Kind of. You need step 6a) do another layer of gloss coat over the decals after you've applied them and before you apply the wash, and also your step 6, "edge highlighting and other colors" is only for colors that are going to get the same wash as the main body. You'll need a step 9a for the eye lenses, pouches, purity seals, or any other areas of color that will need a separate wash -- Dark Angels tend to have cream-colored chest aquilas, so you'd probably leave them blank, then paint and wash and highlight them in between the dark tone wash and the matte coat. Finally, you'll want to apply your final, highest metallic point highlights after the "final" matte coat.I really like the effect you got on the Inceptors. I want to see if I can adapt your method to doing a very dark green, almost black Dark Angels army. Are these the steps you took for them?
1) primer black
2) basecoat black
3) airbrush midtone for highlighting
4) airbrush light tone highlights
5) satin varnish
6) edge highlighting and other colors
7) gloss coat
9) wash with 1:1 mix of AP dark tone and AP quickshade mixing medium.
10) final matte coat
