Here's my critique:
1) Cool looking ship, I like the separate, suspended 3 parts to the ship. I picture the parts rotating around that mini-star keeping them all together, hurtling through space at incredible speeds. I feel like it's probably slower than the rest, with a charge-up cannon that shoots from that star its containing. The design is good, appealing and completely new (though it does remind me a bit of the Protoss). I'd give this one a 7/10
2) THIS. If this isn't the Mukay ship, I'll pay everyone here $5. But if I got it right, you all owe ME $5
I love it, an incredible, incredible amount. It ticks all the boxes. 100% identifiable at a glance. It mimics the physiology of its creator. It, I'm sure, very obviously has a unique special that latches onto passing ships with those tentacles! So fun! 10/10
3) What an agile, aerodynamic little fighter, barely containing a black hole within its confines, harnessing all that dark matter to maneuver with precision and melt away its enemies. Pewpewpew! 8/10!
4) Meh. This one's kinda boring compared to the rest. I'm not sure its purpose, though I like the curved front arms quite a bit. I'd like to see something more graphically representational about it. What's it do? Who's piloting it? I've giving it a 4/10 because it's much less recognizable than its counterparts.
5) Earthling Cruiser, obviously - which, don't get me wrong - that's EXACTLY how it's supposed to be. The Earthling ship should definitely harken back to all our science fiction currently on earth. It looks excellent and well-made, launching nukes from those compartments on either side. 8/10 for sticking with a familiar design for a familiar race
6) The Precursor Artifact - YES. I love the centrifugal force rings. I love that the front looks like it has eyes. I love that each module is shown graphically, represented on screen. What more needs to be said? 9/10
7) I assume this is the ominous dreadnought of the antagonist, and it gets that point across. Though it has a much more ominous dark-matter model... am I sensing some deviation within the same race?!? Kohr-Ah and Kzer-Za maybe? A religious, economic, political or genealogical split? Could be interesting
Except... this design is one of LEAST compelling to me. Just fairly standard, with no real wow-factors. Big ol' battleship guns are pretty cool. I hope it's not the main baddie, though... 5/10
8) Uhhh... is this one being kept a secret? Lol, why is it drawn like that? Can't see it. 0/10
9) OhmiGod! This one's hilarious! It looks like a junker ship made from old semi-truck remnants! That grill on the front! Oh, PLEASE tell me the little pods go and salvage the destroyed enemy ships, lasering apart pieces and bringing them back to the mothership to repair! That would be AWEEEEESOME! 9/10
10) Oh shit, I love this ship. Clean, concise, wholly alien. It's incomprehensible. About as far away from what humans may one day build as a spaceship! I can just imagine what the alien who drives it looks like. 10/10
11) Big, slovenly, slothful, gas-spewing podshi-... er... I mean spaceship. Very fun, want to play! 8/10
12) Yes! Play with the traditional concept of a spaceship's shape. A floating pyramid (or double pyramid, making it a diamond?) works because in space, you don't need aerodynamics, right? There's no air? 7/10
13) I was JUST starting to think - wow, all these ships are pretty friggin' large... where's the little guys? Oh! There you are! And look at all those blasters in the back, this thing must go faaaaaasst. 7/10
14) This looks like a throne, and the small pic even looks like multiple skulls at the top of the throne? Honestly, I can't really tell what's going on here. Could be cool, but until I can see more, I'm giving it a 5/10.
15) And lastly, the evil version of ship #7... or, maybe the MORE evil version. This one's design looks a little too close to #3, in my opinion. And I like #3 better. And unless it's intentional, it looks waaaaayyyy too close to #7. They've gotta be connected somehow. Maybe it's connected to both #3 and #7? That being said, it's still my least favorite, design-wise, maybe 6/10. On a side-note, my 9yo thought it was the best one out of all of them, so what do I know? Lol
