In the way that I have way more hobby time than i have hobby funds, I've decided to sculpt a Hydra.
I'm not a fan of either the old metal Dark Elf Hydra or the new plastic kit. I wanted something that looked a little more like a multi headed serpent.
I started off with a wire armature
Then added a layer of greenstuff to cover the armature and build into a tail.
Heres a couple of shots with 1999 Dark elf corsairs from the bits box for scale.
Since then I've been adding scales in grey stuff. I found a great tutorial over at steamforged.com. for sculpting scales. they have loads of other good tutorials in their painting and modeling section.
I've just got to do scales on the belly and necks then sculpt the heads now.
