I think these two have put together a nice pair of costumes. I like the Rags-esque lenses on Hawkman's helmet, along with the pouched belt which clearly identifies this as the Volume 4 era Hawkman. Hawkgirl looks more like the Silver Age Shayera than Kendra, with her solid yellow top and no midriff. But the belt and weapon suggest Kendra or the reborn Shiera, so I guess this is sort of a hybrid. Also, I really like that she put the earrings in there!
My associate Shag has promised me that there will he has more Hawk cosplay pics from the show, so those will be coming soon!
