Jimmy Olsen vs. Matter Eater Lad

Married to the Blob is the five hundred and fortieth episode of The Simpsons and tenth episode of the twenty-fifth season. The episode was aired on January 12, 2014. Comic Book Guy realizes his comics are nothing if he can’t share them with anyone. Then he meets Kumiko, a Japanese woman writing an autobiographical manga, and he seeks out Homer’s advice on how to date her, ending happily for everyone. I was asked by Fox thru The Simpsons to design a comic book cover featuring Jimmy Olsen vs. Matter Eater Lad for this episode. Of course since I'm on a mission with the Legionnaires it was my pleasure. 
Although it appears a lot of the comic book characters' colors were intentionally wrong. It seems nowadays avoiding legal entanglements it a priority. I totally understand, but at the same time if you are gonna change what you are joking about to the point that becomes something else, it kind of defeats the purpose of parody after 20 successful years and then some.  If it was up to me, I would have colored it like the upper image, with the original characters' color. Comic book fans are the first to notice things like that, most don't like things like that. You want them to like it, they are the majority of the audience.
I'm sure comic book fans would've appreciated it more if it wasn't so deviated from the original.

Is art up to the artists?
