So... this moment is from the classic scene in the JLU episode "Grudge Match" where the Justice League girls duke it out. In the end, they all (well, most of them) have to fight Wonder Woman because some sort of mind control thing. I thought it was one of the coolest fight scenes in the world and I knew I had to draw it. It didn't really start out so serious, just a couple of figures flying around, but I really got into it after a while. I actually had a lot of fun with it, and I was surpirsed I finished it so quickly without totally screwing it up like I usually do.
Besides, everyone likes a good cat fight. And no, boys, water will not be thrown on them, and they will not suddenly rip off each other's tops so keep dreaming.
I also thought it was funny that it looks like Black Canary is screaming at Wonder Woman's butt. She's jealous of her buns of steel.

Clockwise from the top: Huntress, Wonder Woman, Vixen (yeah, she sort of looks like a tomboy), Black Canary (usin' that Canary Cry), and HawkGirl.

Oh yes, FULL VEIW is also good to. Much more detail that way.
