Star Trek Alternate Klingon Designs

Star Trek Into Darkness concept designer Neville Page has posted on his website a series of images that show off rejected concepts for the new Star Trek Klingons. Page committed on his designs saying:

This first round of images are some of the development of the Klingons. This was a very important assignment for me because I knew how important it was to the fans of the franchise. It was a delicate balance of respecting the established looks from previous incarnations yet delivering something appropriate for JJ's film... Part of my self induced criteria was to do a cleaner version (especially regarding the forehead) and to make them sexy (or sexier if you already find them sexy!)
