Artists and animators

Have you tried searching on deviantart ? I know I've come across stuff like that in the past.

This came up on the first page of results for "chubby bimbo": deviantart.com/thunderhotdragon/art/Bimbo-comic-pg-1-829386896

also this: deviantart.com/berserker1133/art/Bulking-Up-Steph-Before-and-After-838355882

and I remembered these two, from my favorites collection: deviantart.com/dr--worm/art/study-on-the-effects-of-high-carb-diets-on-elves-755628740

Not sure if the second one really qualifies as bimboification, since being a bit of an airhead has always been part of her character.

There's probably more out there, but bimboification isn't something I've thought about much.

If you want, feel free to send me a note with details and I'll draw it for you. I'm working on finishing up a story right now, but can probably get started in a couple days.

I'm a jack of all trades

You can find my stories under my profile of course, but here's a link

Part One: fantasyfeeder.com/stories/view
Part Two: fantasyfeeder.com/stories/view

Part two isn't complete, I will finish tomorrow or the next day probably.

As far as the picture, tomboy could mean different things to different people, a link to an image with the approximate look you want would help (cartoon/real doesn't matter). With art, the more detail you can give the better it will match your desires. I can wing it, but it might not be what you had in mind.
