These ship designs look like the more TOS-like asthetic that was originally planned for the Kelvin-era ships in "Star Trek" '09! (Which I *really* wish that they had kept!)
I wish I had a link to some of the concept art...anyone here have any?
Just Google it. The Art of the Film book which I have doesn't have much.
A design I came up recently that sort of melds the John Eaves design with the BOP.
