The aft section of the ship looks... Klingon!
I've not read up on Discovery so I'm not sure where in the timeline this stands, but if it's after the Klingon/Federation peace treaty, it might make sense for them to collaborate the best of both's technologies when producing a starship. I think the saucer section seems a little small, but I'm interested in learning more about the show now. I half expected to see the Starfleet and Klingon sigils combined on that ship. And the music makes this seem a more militaristic themed show.
