OK, I have pictures tonight.
First, the rejects. These are some test sculpts that I did that I decided not to go with.
Group shots:


I was working on completing this one, but didn't like the mouth. Notice that this has no head!

Then I read that the Hounds of Tindalos are emaciated (corpse like) and appear from a cloud of smoke. That, plus so tripping through Google images, led me to try a new look. Rather than sculpt the whole thing, I am converting Chaos hounds to hounds of Tindalos. See what you think:

Some shots of each stand:



I like these better. They were easy to get done. I 'removed' some of the original fur to try to make the hounds look smooth(er), to heighten the texture contrast between hounds and smoke.
Next, I am starting work on some slightly smaller giant worms. I have the Necromunda millisaurs, but it is hard to fit more than two to a Warmaster stand. So I am sculpting a smaller version of the two poses I like best. Once done I would like to have these cast up. I am in the process of adding legs to one worm.

Here is a second pose for the giant worms. The structure I did using plumber's epoxy -- it cures in 10-20 minutes. Work fast! I will cover the basic shape with green stuff. The plumber's epoxy provides a firm foundation for the green stuff. It acts kind of like an armature.

Remember that the worms are the mounts, so I will need to create a few riders before the Dhole Riders will be ready to be daemon steeds. I am considering wraith like riders, flame elemental riders, and skull in flame riders. I want the riders to look both alien and horrifying. So I am still mulling over what the riders look like.
So that's what I have this time. Please let me know what you think about the Hounds. And let me know if you have suggestions for riders for the giant worms!
