Pascal Blanché is a highly talented artist who was the Art Director of the Avatar game before the film was released. I had an Avatar fan site that grew in popularity, and Pascal was one of the concept artists who reached out to me. A number of the film's concept artists contacted me, which was a great surprise for an amateur hobby site. But it was getting top listing on Google for awhile before the film's release.
Pascal gave me permission to display a gallery of his work which is still on my site today. Along with other notable concept artists, Wayne Barlowe, Ryan Church, Dylan Cole, Neville Page, and Jordu Schell. In fact Jordu Schell requested a phone interview which I still have displayed on my site. He was the lead character designer. He has also designed maquettes of the xenomorph. They all gave me permission to showcase galleries of their work, which I still have displayed.
Here's a few pieces Pascal sent me to display for his gallery. I don't know if you would call these "Giger's Alien inspired," but there's some similarities. I see also a bit of Frazetta in his style.....
