Hello. That is a brilliant sculpt. I love David Lynch's Dune aesthetic and you've certainly captured the look of a 3rd Stage Guild navigator. I'm guessing that the foam is the start of the Navigator's spice gas filled conveyance? Have you seen the Dune figures available from here:http://www.bofstudio.com/#They're listed under Shattered Dynasties.
If you click the Dune label it should show you all my other Dune posts which include minis from BOF which i believe are no OOP
