These will represent barbed hierodules, the ones with barbed strangler launchers. They are small bio-titans and are made from 40k termagant bits.
A couple of close-up shots showing the details of their guns.
These are scythed hierodules, with two large scything talons and optimized for close-combat. They're made from 40k hormagaunt and termagant bits.
More close-ups showing details.
These are a couple of trygons, made from gargoyle bodies, ripper heads, and gaunt scything talons. The talons look a little too "busy" to me, so maybe I'll change them around a bit for later versions...
I also put together something larger - an attempt at an hierophant, the largest of the bio-titans. This is made from a warrior body and various large creature bits. I like most of it, but it still sort of leaves me cold. Maybe I can try a different design.
This is the same creature from the side.
Now I just have to start doing some painting.
