I'm not exited about the Phalanx-class. It reminds me of the more-warlike Federation I'm not fond of (As in the stylish Sovereign-class battlecruiser, or Prometheus-class assault cruiser, or even the Defiant-class for example) that turned me away from Star Trek for a while, at least DS9. Also, the "cannon" on the bottom of the saucer of the Phalanx reminds me of the Phaser cannon of the "All Good Things" [TNG] Enterprise-D refit, as does the fins. At the very least, get rid of the weapons pod on top. It seems to make the starship less-streamlined in design as opposed to the canonical evolution in starship design.
So I'm so-so in opinion of this fan design... But it's up to most other people who actually like the design, I feel my opinion a minority, although that doesn't trouble me. *shrug* I think it's actually good for the community to at least have some different opinions on designs for brainstorming.
