The first pic on top features Denise Milani as a busty Wonder Woman from DC comics. The second is Courtney Black as Ms. Jessica Rabbit. The third cosplay pic of Poison Ivy is by Pamela Isley. The fourth is Mad Moxxi [from the video game Borderlands 2, DLC; and I set up the pinup as a motivational poster]. The fifth poster features Batman and Catwoman. And the sixth wallpaper features Yaya Han, also as Ms. Jessica [and she is with two other lovely young ladies, don't know their names].
All right fanboys & fangirls, you guys should be the judges on which cosplay looks the most realistic.... and no, it doesn't have to be the most busty pic in the set. I actually think the female Captain America steals the show, since she looks like she was captured on the 2012 movie set for The Avengers.
There are lots of Yaya Han and Jessica Rabbit pics / cosplay in this blog.
