Ok. At this point I have to ask you to slow your output down a little bit. Or at least make your artworks a little less exciting.
No seriously. I like this one very much. And I have thought a lot about a twin saucer design, because besides a sphere it would be the natural direction to go imo. Makes more sense, and is more exciting then the countless "throwing knives" out there. Also the typical federation look is spot on again....the plating, buzzards and deflector etc add the necessary Starfleet look so there is no misunderstanding what we are looking at.
You made some great designs, but this one stands out.
