Hey, I have been working on this model for quite some time (3-4 weeks). It used baking clay as the base then I added top it using a suggestion of withteeth to use 6:1 mix of Apoxie Sculpt to greenstuff. For anyone who has never tried it, DO
IT! It holds amazing results, detail of
GS, rock hardness of
AS, and smooths like
AS. As you can see, I have the head to do, along with vents for the back, cleaning up and more detail to the gaunt sac, the tail needs to get another layer of clay, some carapace needs cleaning up, and I need to do limbs. I have started on one of the front lower legs but progress will be slow. I hope to cast this is up and sell it but we'll see how that goes down.
