Oh boy, what do I want to see...there's SO many.
Right now I'm pining for WillardDcker's stuff (and that's a lot). For those of you who don't know who he is, he is probably the best Connie modeler this side of Alpha Centauri. He'll be showing up when he gets an Intenet connection again.
In the meantime, I'd love to see the following:
An accurate Titan (based on the version at ussmiranda.com)
A highly detailed Executor Star Destroyer
A highly detailed Eclipse Star Destroyer
More of Azel's Hellions
More of his Neophytes, too
A monster or two from his wild imagination never hurts either
Reman warships! Any one of 'em!
There's more, but I'm keeping this short!
