Artists copying Artists is business as usual. See for instance Marcel Duchamps "L.H.O.O.Q." or that other one he called "Pharmacy"; don't remember what art work he used as basis. It's sampling.
What years are the red period of Dali?
My apologies; I got him confused with Picasso, who went through several "color phases". The image I was picturing in my head, which Batman's drawing reminded me of, was a Dali that I saw at a museum, beside several other very red paintings and drawings. When I remembered that there were several, my brain made the (incorrect) connection to Picasso's phases, which is how the misunderstanding occurred.
So, yes, Batman's pictures reminded me of some of Dali's work; but, Dali did not have a "red period".
