From the Shirtpunch.com's interview with the artist:
"Question: What inspired this design?
Answer: I have always been a huge Army of Darkness fan. Bruce Campbell as Ash kicks all kinds of arse! I had this idea quite a while ago when considering zombies in the Star Wars universe. Which lead me to imagine the most epic team up: Ash from the Evil Dead Trilogy and Han Solo from the the Star Wars trilogy. “Trapped in a galaxy far far away.” If Ash can be transported back in time why not be sent way across the unverse and perhaps battle the Deadites who are taking over the empire… For me this would make an awesome film or comic. Question to ponder since both Han and Ash are both pretty frickin’ awesome, who would be the side kick between the two? I leave it to you to debate."
