Batman and the Flash: 'The Button' crossover event!

My next project has been announced.  Its a mini project as I will be joining writer Tom King on Batman for two issues!  Here is the press release from Newsarama:

Almost one year after surprising the comic book world by hinting at the merging of the DC Universe with Alan Moore and Dave Gibbons’s Watchmen world in Geoff Johns’ DC Universe: Rebirth #1, DC is getting ready to start offering details into the mysterious connection for the first time.

Publishing in April as a four-part crossover between Batman and The Flashongoing series (#’s 21 & 22 of each), The Button will be written by Batmanscribe Tom King and penciled by Jason Fabok, along with The Flash writer Joshua Williamson and artist Howard Porter, respectively.

“The two greatest detectives in the DC Universe unite to unravel the mystery behind a certain blood stained smiley face button stuck in the Batcave wall,” reads DC’s official description. “However, what begins as a simple investigation soon turns deadly when the secrets of the button prove irresistible to an unwelcome third party – and it’s not who anyone suspects! This is a mystery woven throughout time, and the countdown starts here!”

DC also reports that each issue of The Button will feature a standard cover for the $2.99 edition, along with a $3.99 edition featuring a lenticular cover, all drawn by Fabok.

So here is the cover I came up with, which will be a 3d lenticular cover that changes between Batman and the Flash.  Below is my process of creating the image.

Colors by Brad Anderson and a final animated preview of how the cover's lenticular effect will work.

Layout #2

This was layout #1 but it was decided that the two characters should be dead center.  The original  layout was given to me by Jim Lee.
