This Supergirl/Mary Marvel commission is part of a set featuring superheroines who have been turned to stone by Medusa.
If you're wondering why their costumes are ripped, apparently Medusa has a fetish for ripping off clothing from her petrified victims. I'm looking forward to doing more drawings like this. Look for more in the future.
