I'm planning to have a more screen accurate 1/6 Dewback 3D sculpted in the next few months.
This SSC Dewback is a great piece - it conforms well to the iconic (though limited - only really shoulder and head visible) Dewback pic from ANH - but with the chicken feet, stubby tail and the too-wide head, I'm wanting something closer to the actual prop.
I've amassed a ton of ref pics and just looking into sculptors now. It's going to be slightly idealized due to the roughness of the prop construction but key for me are the rhino/elephant type feet/legs, a longer/thinner tail, narrower head and a more accurately proportioned body. Adding some fur to the neck will also be essential.
Sounds lie an exciting project. What are you plans for the saddle?
Actually blurrgs were a Phil Tippett creation that first debuted in the live-action 1985 Ewok Battle for Endor TV movie.
Interesting side note, that one was a full cinema release in Australia where it was called Ewoks and the Marauders of Endor.
