Dina takes a lot more work to look human, IMO. Her shoulders, even with the fix, look strange, and the hips are NOT realistic, especially with the water ballons strapped to her chest. The few realistic looking Dina renders I've seen have the character at an angle to hide several body issues. Vicki took a bit to make the face pretty, but overall the body is more realistically proportioned, though mroe athletic than most females. It's easier to make her more ordinary than Dina, especially if you get Vicki 2, but even Vicki 1 is okay. The best thing to do is to look at the postings in this forum for Vicki and Dina renders/textures, etc. to decide which one you like more.
