Tried an earlier version of this last year, and thought it was great. Came back to see how much work was put into this, now, and holy cow.
Kudos to you, Horoichi. This may turn out to be a prime one, IMO.
One thing I would suggest, if at all possible, is to add thicker sizes to the lower body, as well. Bunny Booty needs a little lovin, too, but aside from that, this is looking pretty golden.
Please keep up the good work.
