I'll give you the quick and dirty rundown and see if you find it interesting:
Corona is a hybrid tabletop game incorporating board game elements into a story-focused RPG. Players are members of the court of a psychic god-king in the far future, maneuvering to deal with the threats that not only pressure the solar autarchy from outside, but also the intrigues of potential treason within.
The art I would be commissioning would be three or four two-page splashes between the sections of the book (page size is 6"x9", so approximately 12"x9" landscapes). Looking through your gallery, Lost World and The Passage have elements of what I'd want: technology, especially massive architecture that both draws on ancient existing structures and yet is clearly advanced and evolved in both design and material, integrated into natural environments.
My budget calls for $75 per piece, which we can negotiate somewhat. I try to maintain artist-friendly practices with the freelancers that contribute work: you would retain rights to the work, with my rights constituting a license to use the pieces in the book (obviously), as well as to promote the game.
I can provide you more specifics if that piques your interest.
