I was browsing through the Web when I saw some of these old favs... they just inspired me to draw more sci fi styled art. Artwork by the skilled digital artist and colorist, Chuck Pires. His art is a form of the Cheesecake style. And he has a cool gallery on Deviantart.
The Infinity Poster was for a table top game, dating back to 2007; so I doubt it was connected to the Disney Infinity video games. The last Marvel poster with Red Sonya, She-Hulk and Psylocke is very dynamic. I suspect that he started out with a plain background and then he added all the special effects with Painter / Photoshop...
