The fighters are pretty good, I'd try going a little bigger so the 'wide triangle' theme is more obvious, they look like the tip of a Dorito.

A boarding craft has a bad case of bloated whale syndrome. I advise making it pointy so it looks like it could punch through a ship. Maybe elongate it a little, flatten it some.
Pegasus could use a little more... angularity. It's bulky and unshapely, but that's okay because it's heavily armored. A new color scheme would be nice, along with some more shaping of the prow area.
Make the Centaur a little larger than the Pegasus, just add a rectangular carry bay on the belly. Otherwise, see Pegasus.
Hercules is large, large adds points, but it's a bit flat, I'd make the nose pointier. The change from the fore to the aft section is rather drastic, too.
Labyrinth: That you have there is a stone ball with a *.
Basilisk is interesting, but too round. The front half is fine, but the back could use some deviation from the ellipse.
The Egg is so cute, it looks like it could give you diabetes just from being so sweet and cuddly.
Lemnos is too elliptical in profile, the top view is good. It needs some variation in color.
Faun: That mech looks like a constipated Fireant skeleton.
This is a Fireant VV
minotaur: is this what you were going for?
Sabertooth is small.
That missile looks odd, and not in a good way.
That gun looks odd, and not in a good way.
