The pteranodon was originally drawn for panel 2 on page 6 of my 2010 comic Martian Debut. The Geisha was drawn for panels 5 and 6 on page 11.
The bubbly sphere is unused artwork created for panel 6 on page 5, panel 3 on page 31 and panels 3 and 5 on page 34. I wanted to show when images were being processed by Mars itself and ended up using more of a closeup.
The gas mask in the background is a printed composition from 2009 using a photograph I took in collage, between 1995 and 1997.
The 4 images were collaged together in 2011 with glue, paint and a marker.
