I've done a bit more sculpting on them, but I think they are nearly ready for paint. Here are a few quick snapshots:
weird mutatey texture on the plasma arm:
head slime and fleshed-out flamer arm:
heavy bolter veins:
and a size comparison!
I just got a new batch of GW green stuff, and I found it a lot nicer - they now sell it with more yellow than blue, which seems a lot more workable (you can see the difference in colour on the models).
There are perhaps just a few things I want to address - some of the boils look a bit too much like balls sitting on flesh, so need to enclose them a bit more, and also I'm concerned that their legs currently look a bit plain - do you think some boils or fleshy parts would improve them? An early plan I had was to replace some of the armoured feet with erupting flesh feet. In fact I might try doing that on the melta oblit, as his left foot could be sculpted quite nicely over the barrel!
Also, I am having a bit of a dilemma about how to paint them. One thing I'm sure about is that they will NOT follow my standard colour scheme. The fluff makes it quite clear that they are basically 'hired guns' who don't conform to any particular legion, so my challenge is to paint them in colours that are complementary but distinct from my army. I'm currently thinking of going for a darker brown armour, maybe Scorched Brown layered with Vermin Brown, possibly with standard metal trim (rather than rust - but I will probably end up painting them rusty anyway), and for the flesh, I have some Tallarn Flesh foundation which I might apply Rotten Flesh to and then use some red and blue washes over the top (and perhaps even paint on some small blue veins).
What do you think?
