I like the original, but this mash up was pretty good. Makes me wonder what an official Blade Runner and Alien Universe would be like.
The basic idea was just looking for a different mood for this picture. But yeah blending those 2 universe would be risky but interesting.
Coincidally enough, it was an idea early on in the development of Prometheus to have Batty to appear at one point in the movie (becoming what working off world was ?)
You can see it in the making of Prometheus,
