One thing I really love about Moebius panel art is that most of his panels can be isolated from the story, enlarged, and be immensely appreciated on their own merits. The panel below could be a framed print on my wall and be most satisfactory to my sensibilities.
The complex simplicity, the perfect perspective, the sense of depth (that this plane is really in the air), even the sense of mystery (what's unfolding here? What is this place?).
I think I'll post some more of his panel art.
