They're very good work, although I don't know that I necessarily like them as reboots of the originals. It certainly gives a good idea of what the ships would look like if Paramount ever tried to produce "Star Trek Redux" or something along those lines. (oh, horrors!
:p)
I think it would be really neat to see these in 3D renders, though, because all three ships would be excellent stand-alone class variants, along the lines of
Dennis's
USS Concord or
Anarion's
USS Churchill.
