The Taurus looks nice, a proper original TOS Fed ship that looks vaguelly different from the Connie but doesn't involve nonsensical re-arrangement of components like a bizzarre mix'n'match. Some elements remind me uncomfortably of the New-Orleans, or Bernd Schneider's Sirius class from EAS. But it's carried off very well, the ship looks convincingly like something that might have actually been on TOS.
