Disregard >>11302389 this unless you're trying to make the most dry, unsexy narrative possible.
Something to actually consider is the tone you want- do you want to focus on the more realistic (without getting into the autistic) aspects of such a drastic change? Or is it something more along the lines of an ecchi comedy? Whatever you choose, for the most part choose a tone, a logic for the world (is it porn logic, is it our logic, is it pants-on-head retard logic, IE Felarya or some turbo NWO) and try to stick to it. A few threads back that elf story was brought up because the opening chapter goes something like "tee-hee we're elves and we like being big but sometimes we go a lil' too far but it's all in good fun!" then four chapters in you've got whole nations being made into anal beads and other manmade horrors beyond human comprehension occurring, and it throws people off.
In short, know the feelings you want the audience to feel, and then have the writing convey those feelings.
