Klaus Pillon is a French illustrator and concept artist.
His atmospheric landscapes and environments are often cast in limited color ranges, with an emphasis on tone and accents of color to provide focus and drama. His command of atmospheric perspective and soft edges allows him to project a feeling of large scale in many of his pieces.
The number of pieces on his website and blog are limited, but there are more on his deviantARt gallery and CGHub portfolio.
There is also a gallery of his work on ImagineFX, which is where I encountered Pillon’s work.
