That's a quite fun idea, SGD, and pretty well executed too... but there's one little detail in one of the pictures that I can't pass by without a bit less positive remark.
The middle picture in the third post (where the two tiny ladies are tickling Shamila), there the two tiny ladies are bend over. They are naked, so their breasts are not supported (by e.g. a bra). The problem is that their breasts are shaped/angled exactly as if they would be standing up straight. In the position they are placed their breasts should also be affected by gravity, but that means that they should be hanging down (and not along their body, if that makes sense).
I don't know if it is possible with your tools to do this better/right... just something that I can't look past in this picture as it is a bit too obvious. A pity, because it's probably my favourite one of the whole series.
