As long as it gets to either gigantic or monumental i'm sold!

O.o oh my god!!!! i feel raped :C
lol XD

tits are tits no matter what size!

Flat to Huge, as in any size to basically D-sized. :3

average to huge is my favorite size range XD

the best BE are from normal, or maybe "big" (DD-F) breasts to "Huge-Massive-Xtreme or Giga" as limit fur a funny BIG BE

-bests BE are those where some top, bra, shirt, etc are busted XP aslo puffy fat nipples are lovely, specilly if the drip-spray milk when they reay "huge" and bigger sizes.
-Suden fast and big BE fur the 1sts pics look gr8! ya know giving that "boom" growth effect, then the growth can slow down a bit but keep constant.
-In those 1st fats growth pics, if they hit something or some1 it gives a naughty effect. Specially if they hit some1s face in that "boom" effect.
-When they overflow hands,beds, chairs, descks or eany other surface also looks gr8
-last and taking a step further, if by eany chance the boobs end on top of the girls face (mavy cos she fall to the growns with "boom" effect or maybe because the BE takes place in a reduced space, a car, phone-cabbine, a box XP or even when there are 2 girls in the BE and the boobs squeez against each other XP

I hope this ideas help ya ^.^
and if ya really enjoyed 'em can I have a simple BE pic of me character? ^///^
(cant blame me fur trying. I do have a human form if needed)

Mmm, I'm fine with a decent range, but flat or average to notable is preffered.

'Notable' to 'Huge' gives a better 'HNNNNGH!-GRRF!' feeling than others. (lol) In other words... that particular transition has a more appealing effect on the senses than 'Flat' to 'Gigantic' or 'Huge' to 'Gigantic'... but then I don't really see a lot of 'BE' artwork that I like besides yours. Jungle De Ikou was an exception for a while... but then the design for the faces for the females started to get on my nerves. It's only a 3 episode OVA... and they could have done better with just a pinch more realistic designs for the characters. For fanservice anime, I'm a fan of the Dragonaut: The Resonance/Witchblade anime-type-style. I like the fanservice in Desert Punk... but that anime is more about perverted humor than fanservice. Anyway... 'Notable' to 'Huge' gives a better feeling of a gradual transition with the awesome squishiness of soft flesh VS tightening and tearing clothing.

Massive is a good ending size. It says I'm here to party but I'm practical too! >.<

Id go with "Flat to Taboo". but all of them is googd.
