In order to make this a lot more realistic, you ought to break their spines and twist their waists to inhuman measures. The result being that somehow in their broken mangled bodies we manage to see the breasts and the butts as well. This is how comics work. Fact.
This is a really clever idea! If it wouldn't bother you too much, I might try to do something similar... or maybe in reverse (super-heroines in princessy get-ups?). I'll credit you with the idea, of course, and link back here- if I actually do it.
I love these as well! Ah love all of them! Wish Disney would do a little cartoon series about them as super heroines! Now that would be something awesome than their Hannah Montanna! And love how creative you make the costumes! Including aspects they had into them!
