I've gotta put my two cents in on this.  I think these ships look terrible.  The federation designs are not balanced or aesthetically pleasing, they look primitive and cartoonish.  The Klingon BOP is especially disappointing.  They have clearly not concerned themselves with making it look accurate.  They should see LC's work on ST:Excalibur.  The ship they've built simply doesn't compare.  And while we're talking about Excalibur, the STO version of the ship is just atrocious.  There is an obvious design lineage/pattern that all star trek ships follow, and they don't go for a "retro" look.  Starfleet is not about "retro".
When I look at these screenshots I am struck by a single thought.  These people are not Star Trek fans, and they don't understand it.
