I tried to come close to the fantastic concept of the Sakaaran by Jerad Marantz https://www.artstation.com/artwork/69kx. It took me 3 hours of sculpting and texturing and 2 more to export, bake, control the Surface and light the model. It´s rendered in Realtime (but i use passes). The Model contains of 25 000 Polys. I know its not exactly the Concept but Speed was a important factor because the sculpt was just to free my mind a bit.
Have a nice day!
