Concept designer and illustrator, Maciej Kuciara, has recently posted a collection of concept art from his work for Creative Assembly’s recent “Improvise” CGI trailer for Alien: Isolation, including unused key frames from the cinematic. You can check all the images at the artist’s website here or below.
I'll take traced stills over inferior "original" designs.
The airducts part had thing one particular shot that looked exactly like one of the shots of Dallas in the airduct. I like how they also included a hint of the low rumbling instrument-I-cannot-name that played during the scene Dallas hunts for the Alien.
Ahem...
Some really nice stuff - but to be fair, some of it could've been traced from Alien stills.
