I find it easier to paint from the recesses outwards, so the neon sturginium engine, the blue behind the black plates, the black plates:
Metallic on the black, then the fill in blue:
Ink on the plate lines and rivets, red/orange airlock cover:
Ink and highlight on the cover, blue layering. Some colour on the funky round things on the nose. Green ink on the metallics, on the back model:
Copper pipes. Pretty much done!
I might have time for a mixed group of 6, 3 of one type & 3 of another, before the end of the month. It's going to be tight.
