I imagined that these tough customers escaped from another dimension (shades of the Armorvors), discovered a planet in the Glyos System and then settled there. They named the planet Granthan, after their race.
While working on the Armorvor project, Marty, Jason and I collaborated on a number of head designs. One character that I really wanted to see realized as a sculpt was a Granthan. For the specific look, we went with the non feathered style (there are variations within the Granthan species), representing instead a more classic "dino" aesthetic. The Armorvor body type was a great match (even though the original "Grathans" has tails), and Marty did not hold back on the jumbo sized noggin's dimensions! The final result is one my favorite sculpts that Marty has ever created.
The above sketches detail the conceptual process, showing the direction that we ended up taking for the overall vibe of the final piece.
More Granthan action later today!
