Well he did ask for feedback on the genitals so ladies, compile your lists. I agree that what's shown is looks pretty much like a 'tick off that box' feature but I guess he gave it what he thought was reasonable. Looks to me like doing proper labia majora and minora, clitoris, clitoral hood etc. would require more polygons and if you want realism, enough morphs to accomodate natural variation to some degree. You also need a good selection of detailed textures that would work decently with different skin tones. I haven't seen anything, including the add-ons that really is all that great. 

For something built into the figure, I reckon the thinking is usually that only people who do 'porn' would want that level of quality. How long was it before DAZ deigned to give Vickie a 'crease?'  I don't think it's lack of talent or reference material, just a perverse notion that it isn't needed - or is it that if you need it you're perverse :-)
