Wow you can definitely tell this is Supergirl and Jean Grey from all the context given by their outfits and unique character designs. Definitely isn't just two random chicks with the right hair color, nosiree.
I understand the artist has a limited range with a bit of sameface syndrome at times, but that can be made up by giving the characters some context, like clothes, or specific recognizable hairstyles. But if he can't even be bothered to do that, then I don't know what to tell you, duder.
