Hey mate, sad to hear about your loss.
I really think you did a great job on the prop. Just bought it and currently having a play around with it. First things I noticed was that you went for geoshell approach for coloring. While that is fine for DS, I would LOVE for you to to a quick UV for just the labia and inner parts. That way it would be way more versatile for people who want to export to other apps and create their own textures and overlays with still good details on the lips etc, and not using the geoshell for that. Could you add this feature in a patch perhaps?
Other than that I do like the morphs you created so far. Has a good level of realism to it, but as others said already, shaping morph package needed! :) I am already working on my own custom ones but cannot ever have enough of those.
While playing I also stumbled over some issue. The joints for the rectum etc seem to be misplaced or maybe it comes from dialing FBMs, but take a look at this. With the joints so far out, the rotation centers are all off so when trying to pose anything on the inside it becomes quite a mess.

Other than that the posing deformation works really well so far. Pretty close to what you get from the 3fw prop which has been the gold standard for me for ages. And I absolutely LOVE LOVE LOVE that you thought about adding anus base joints etc so you can properly move around these parts without having to resort to a ton of morphs. This keeps the area clean in terms of topology and its easy to fix little quirks by just moving things around. It shows that you are someone who was probably fed up with this aspect on other props. Nicely done.
If you can fix these issues above it is probably going to be my go to prop in the future.
