[1] His first comic book work was a collaboration with writer Alex Grecian on Seven Sons, a graphic novel based on a Chinese folk legend.

For Green Wake Rossmo adopted a limited palette, using different colors to indicate different times or states of reality in the narrative.

Co-written with Alex Link, the remote wilderness setting in the story was influenced by Rossmo's experiences canoeing at Waskesui.
