Supergirl in Peril

I had originally intended to do a cityscape as the backdrop for this picture, but it was becoming much too difficult, so I opted to do a simple cliff instead. Apparently, this version of Supergirl was really just a shapeshifting imposter, so she wouldn't really be vulnerable to kryptonite as her true Kryptonian counterpart would be, but I like this costume the best, so it's a bit of license.
