Here's a starship design I've been working on for a while - the Integrity-Class, which I imagine was launched in 2200.
Halfway between the NX-class and the Constitution-class, this ship borrows from both eras of design. Also, imagining that the USS Kelvin was launched sometime BEFORE 2233 (maybe 2215, given that the Kelvin appears pretty used when we see her), I chose to borrow lots of elements from that design as well.

This animation uses an extremely low-poly version of the ship, which I'm slowly re-modeling into the high-detail version.
