I know it's only one picture and you've probably got a lot more, and you've probably done your research, but I have to ask the bad question: is Skipjack's periscope fully extended in that picture?
I do agree that the hulls while surfaced are definitely odd-looking. On the other hand of course external views are hardly realistic either.
Not arguing, and I'm looking forward to your progress with interest. I just had to ask.
