Hey D6rk, thanks for the explanation. Personally I think the trick is to make the LIs especially their facial features softer and sweeter, NOT younger like underaged lolis. It's hard to describe in words, hence I can only use two recent games Haunted University and Desirium as examples.

None of the characters in these two look underaged and can definitely pass off as adults, but they manage to avoid this very rugged and coarse look that plagues most Daz models.  Let me try to illustrate the point as best I can using Haunted as an example.

This is a typical character that looks  anywhere 18 - 22, she has facial features that look "normal" and somewhat sweet.

A blond character that has a more outgoing and confident feel.

This one looks older and perhaps closer to the "Daz feel".

This is obviously going for the kawaii fans, but most importantly doesn't look loli.

Just using these characters as an example to illustrate what I'm trying to say, naturally all rights belong to Axolotl Games here and screenshots were contributed by players in another forum.

Naturally you shouldn't follow them exactly as I'm sure you will have your own artistic style, I'm just saying your current screenshot is showing something too close to what most other games using Daz are doing. This means the art won't stick out, so you will need to lean on some other thing like a strong story, sex scenes, game mechanics etc to rise above the competition.

Hope this helps. I can't speak for the "community" so just my personal 2C here.
