But you can't apply the same standards to all people. If every girl had large breasts it would get boring really quickly. Variety truly is the spice of life :)
As for these two specifically, Selene would look weird being busty, since she's supposed to be 11. Even if she's depicted as an older teen I think she looks better being smaller. I can go either way with Dawn, I've seen good art with her flat and busty.
