Unless you remove your restriction on face claims, your going to have trouble recruiting for that RP. A lot of the superhero RP players aren't going to play if you don't allow cartoon-ish faceclaims like a picture of batman or something.

I always restrict my faceclaims and in my experience I have never had difficulty recruiting for an RP. If 'cartoon-ish' faceclaims don't match the tone and setting then I respect the GM for restricting them. If that's something that doesn't appeal to you as a player it makes more sense to move on then to try and force the GM to tailor to you. There's plenty of other RPers on this site and there's plenty of other games, if one opportunity doesn't work out, it doesn't take long for another to appear.
