i didn't realize what it meant until it was too late, i would have chosen normal!

I'll just make my own category. Normal > Overboard. ^^

For me it's more about the growing than the final size.

Normal -> Big. Ooow..... I like that elves got boobs.

Large-Huge

Varies. For drawing, as anyone who's seen my folio can see, I tend to draw from Normal up to Big, though I have some characters and drawings that are Normal, Small, Petite, or Huge.

What I prefer to see varies on body type. A long, slender build, I'd rather see something from Petite up to Normal, a more average height/width ratio I prefer to see Normal to Large, and a thicker build (what some would call variously 'broad', 'stout' or 'chubby') with solidly Large or occasionally Big (though Normal can work nicely too).

Given the varied response there, I'm not going to vote since I'd need one and a half or two votes or something to cover.

Can't draw small boobies.

Big boobies are better.

Fictionally speaking, definitely big to massive. But fiction /= reality. In the real world, most likely normal to big.
