Now I am watching the Enterprise episode "Kir Shara"...
At one point Enterprise is with a small andorian fleet, and i've noticed a smaller ship than the Cruisers.
Unfortunally the ship is only visible in low detail, but from what I can see it is basically the same shape as the cruiser only with "wings" pointing downwards, and a tailfin, (see attachment) and roughley the same size.
I will be making this ship as soon as i'm done with the Manta, but if someone would like to take a crack at it go ahead too.
