Here's one of four images I did for Warner Brothers recently.  This was a marketing project as opposed to a comics project, so don't expect to see this on a comic book cover anytime soon.  In fact, this turned out to be some kind of test thingee, and the art will not be used at all!  Although, I have heard rumors there are plans to print it on a roll of toilet paper in Guam...and then  there is an adult diaper company that wants to print the art on the "load flap" (whatever the heck that is)... personally, I made it into a nice reflective sticker that goes on my mom's cat litter scraper.  She's really happy with it.
