As far as I'm concerned it's the faces that are most detracting (on both Allison and Ryan)--I like to use maps with body hair and I like to have facial hair options and Ryan has none of these and it's not worth my time to try to make my own textures for them.  Deecey did a good job on the Runtime DNA forums making Allison look pretty--but to me it's not worth the time.  Antonia is more real world looking and I like her for that reason--but even though she's no fashion model she has a realistic average worman look.  

I guess it depends on what type of work you are doing--I've often found that people have said the native Poser people were more realistic looking--but I don't know people who look like them--perhaps James but that's about it.  If you are going for "real world" types of scenes, I suppose these figures are ok.  I can't put my finger on it, but there is something off putting and not quite real about Allison and Ryan.  People on other forums talk about the "Uncanny Valley"--although I'm skeptical about it I do confess there is something subconsciously unpleasant to me about them.  

In art, conventional as well as digital, I don't think people much care for looking at unattractive or average looking people.  I think that M4 can be very real world looking and that's what I liked about Apollo--not so much with M3.  When I first started working with CG images if I created images with heavy people or those that weren't ideal looking people did not like my pictures.  Of course the artwork was for myself, but I like it when I can share things I've created with folk and they like them.  I don't think I would have been published in magazines or on a calander if I'd used the native Poser folk.   For many people working with 3D art is like a sort of fantasy fulfillment--Barbie in her dream house, heroic images,  modern Adonis'.  I don't do much in the way of fantasy work--but look at the covers of paper back novels and go back to Tarzan and Conan--the artwork of Boris and Frank Frazetta--did these stories and images make one think of average looking people--if you put an out of the box Ryan in fantasy garb and put him on the cover of a book--how many books do you think would be sold?   Even in ad work--unless there is some sort of comedy going on you're not likely to see average looking people unless they are trying to appeal to a certain market.

This is highly subject, of course, I can only stand my what I like.  I don't feel that the Daz Figures are highly unrealistic, it's the morphs that people apply to them--and more people want super vixens or muscle studs rather than cranking up the love handles on Michael, sagging Vickie's breasts, or giving them crows feet.  

I liked what I saw of your model Shane as he looked to hold great potential.  Please keep up the good work!
