I got my hands on a cheap army

now to do the best with what I got.
I bought the
DG parts from 2 startsets and some Easy to Build kits. (assembled, and "touched" with some paint),
1
DP (partly assembled, and missing some parts)
2 Vindicators (badly(!) assembled)
and I bought new:
1.Plagueburst Crawler and a set of Blightlord Terminators.
Got most of my conversions done. And I would love some input, or ideas to what I can add before I start painting them. I am still going to go over all models fixing gaps, and scraping of moldlines.
The painting theme I am going for is "abandoned heavy industry". So it's going to be a lot of rust, no live fire on any models, gray skin on daemons and most of the exposed skin, removing most of the "bling" (bells, horns, and mutations), and to contrast the dark brown rust I will use bright green slime/toxic waste.
PlagueMarines with BlightLaunchers. They got to have blightlaunchers!
Left Sorcerer in Terminator armour, with staff and multiweapon Made from one of the blightlord terminators with the flail. Middle: My chaos lord. Made from the lord in the startpack. Right. Blightlord terminator (going to be used as the one with the flail). Also from the chaoslord form the starter.
Back of sorcerer. It is hard to do anything with the back of the chaos lord model.
Cultists. Its Poxwalkers, but with guns, and less mutations. But it's still more poxwalkers than cultist... They will be painted with more "living" skintones and brighter clothes, and hopefully stand out enough to pass as cultist. (I can see now that I have forgot to fill in some of the "worst" mutations.)
Daemon Prince. Small wings, but it is what I had in my bitbox, and I like how they look on him. Somewhat of a bumblebee look, its nurgle after all.
I am not that pleased with the back after I undercoated it. I will work some more on the model before I paint it.
Plagueburst Crawlers. I had a lot of fun converting these boys! Tentacles, and daemon skinn showing in the back, are going to get a layer of Lacquer, removing all texture left on them, just a smooth surface.
