Seems like all the cool designs out there are with the Terran shipset.   Though I did see some cool ones with the Torian set.  
So I figured since no one else really seems to be posting pictures with the other ships.. id take a crack at making some Yor ships.
couple things:
1. I love engines..if you dont like lots of engines you wont like my designs.
2. I didnt necessarily try to go for a "Yor" feel as much as just trying to make stuff that looked good.  
3.  I tried to stick with a theme in the design.. so you will see alot of the circular engine thing.
anyway..that being said... I have finished 4 designs (and made one fun one).  This takes longer than i expected so im probably not gonna get them all done today 
 
Here is the first.
The Sparrow.  Tiny hull.  Not real detailed because I see Tiny hull ships as just a step towards your real fleet.  I tried making my entire military tiny hull ships once... it was actually pretty effective..but I hated all the micromanagement.  Anyway..here it is.

Next is my small hull ship. The Catfish.  If you think these names suck, thats cause I dont put any thought into them hehe. These are just templates and I end up renaming it every game once I put engines and weapons on it.    Alot of the Yor ships seem to be very "fish like".. so "catfish seemed sutiable.  Also..you might notice that I have a problem when it comes to Antenna.  I just cant stop sticking them on my ships!

Medium Hull.  now we are getting into the fun stuff.  Unfortunately I couldnt really find a medium hull for the Yor that jumped out at me as "cool"..so I ended up taking one and just covering it up with other stuff 

.  The result is the Stargazer.   Pretty neat ship I think.  (BTW: I just noticed that a stray antenna got placed on the ship in an ackward place.. if you notice it you get a cookie)

And next is my Sensor ship.  I really wanted to make this guy so I put large hulls on hold while I did it.  I love my sensor ship

And lastly.. one that I just made for fun.. I give you "PTHHBBTT!"
