Accurate reference help?!

[SonieTheDog]

Ok, so I'm making a bust chart for my 4 female characters and I'm wondering if it looks accurate? I'm not really one to draw breasts on my characters so I really don't know.
This is mainly a reference for other artists when I commission stuff. I'd like it to be as accurate as possible.

Also, yes, one character is much shorter than the others. It's because shes a Rabbit lol. They're short.

Cup size is really dependent on the difference between ribcage size and the circumference around the whole chest (not breast volume). So no, these aren't accurate cup sizes. These characters would all probably be about the same cup size, excluding miss AA.
