The Orville: New Horizons’ Dinal Alien from the 3rd episode entitled "Mortality Paradox."
I explored variations on the glowing lines, in glowing and neutral / not glowing states, ear options and possible vfx post work. This was a 3D / 2D composite. A lot of nuanced changes between these designs, so they all seem very similar. Screenshots of the final makeup and applications at the bottom of the post.
(Costume was not created by me and was just a placeholder.)
