I don't exactly know how to rate this.
The animation seemed quite solid.
The drawing can use improvement in many ways, even though nothing looked disformed, it could be way more polished (and her tight butt kinda looked... well weird).
The ides and most scenes were basically taken from the other video, but this animatin was a big improvement. While the original seemed kinda rushed (or the program used for that was just inappropriate), this one really got me thinking, there is a lot of work in it, combined with skills that yet have to improve.
So yeah, I think 3.5 stars are kinda fitting.
