Gary, take a bow my man-this is definitely your BEST by far. I'd definitely rate it around a 9.5 to 9.8 out of 10. There really are just a few *really* minor technical issues I think are worth raising.
1. After the first girl shrinks, the bra next to her looks like it has changed back to a smaller size.
2. After both girls shrink, their clothes are in a different orientation to the previous scene.
3. There is still a small issue where you show the girl's underwear shrinking with her-though this is far less glaring than it was before.
As far as 3 goes, have you considered doing what you did in Call Girl collector in the final stage of the shrink. So start with the gradual shrink-with the clothes getting larger. Then, towards the end, have the girl suddenly drop down below camera-cutting back to her at her new, much smaller, size. That could eliminate the problem I mentioned all together. Anyway, just a thought.
Aside from these 3 minor issues (oh, & the voice thing-definitely agree on that), this is truly superb work Gary-you've outdone yourself this time! Look forward to your next SW outing with great joy
