I really dont want to hurt any designers feelings since Ive loved your ship and station designs up till now and it didnt bother me so much at first since I was just exited to start the beta, but im not that impressed with the envoy ship designs...

1. TEC- As has been mentioned it looks too much like the constructor which is bad in two ways: confusion and being a design that just doesnt say diplomatic cruiser. I know It needs to be a bit industrial looking to look TEC but you were a little too successfull on that front.

2.Advent- Looks like Santa's intergalatic delivery ship. The general design looks cool but the corners curling up and ending at little balls makes It look a little rediculouse. It does make me think that its undermining planets by dropping presents, which is an amusing enough thought.

3. Vasari- The one I have the least complaints about as it generaly looks ok but it has some aestetic issues. For one its boxy design makes it look like a model that belongs in the origional half life where they couldnt have too many polygons. two, this sharp cornered design looks very un-vasari as tipicaly the body shape of vasari ships and stations have been sleek eliptical shapes with pointy things comming out of corners. 

As I said non of this is meant as insult just simply critique (the Advent one is really the only one that bothers me while im playing) and we will have to see from other responses as to whether im totaly off base with them.
