Below are the ship designs I submitted for the contest. I have to commend the players who can design appealing Altarian ships. Their ship parts are, to me, the most visually appealing, but they are SO hard to work with.
Huge Terran ship with rotating habitation modules and mount points for weapons. The "Stardock" is cheesy but I was playing with how to add wording just using the ship designer.
A very simple (part-wise) large ship made with Iridium parts (as the Terran player).
A very simple (part-wise) medium ship made with Altarian parts (as the Terran player--would have looked better as Altarian, I think).
I'm probably one of the few who enjoys designing non-combat ships. This is a Terran colony "Bling" ship made with all Terran parts and counter-rotating habitation modules. For me, the early game is dominated by colony ships and I want mine to look awesome.
Finally, my personal favorite of my five designs, a Terran freighter "Bling" ship made with mixed parts. The habitation ring rotates (as you may have noticed, I saved the habitation ring as a custom part, along with several other parts from the colony ship (which I made first.)) The "joeys" (cargo modules) are a separate part, so this ship could be converted to an assault ship with Troop Modules. I also added more bling to the shuttles and shuttle mounts forward, forward-facing thrusters on the bridge module, and the Interstellar Shipping (ISS) logo to the bridge module (hard to see from the angle I have the ship at).
