Whether they're 'counting as' Guild Hounds, Canine Remains, Night Terrors. etc. the closest match in the Hellraiser franchise is going to be either,
It also helped that there is a model in the Games Workshop Dark Eldar range that could be adapted for just that purpose ;-)
It's more a case of what I've removed than what I've added but for your reference here's the model I adapted,
I may add a few more straps before I call them complete but they'll do for now.
Thoughts and comments are (as usual) most welcome.
