I've filled in most of the gaps with glue, then painted over them. This way, it's not so obvious. There's a few things I would have done differently, given the chance, but I had to work within the rules of the Kontest.
I wasn't sure at first if the green globes with copper trim would work, but it does; these power collector modules (or whatever) have a distinctly alien look to them; I figure Hoshi captured them in one of her first raids with the Defiant before this ship was commissioned.
The stand gave me a LOT of trouble. I had to embed it inside the deuterium tanks, rather than just having it stuck to the outside of them. The contact point was just too wobbly otherwise. It's not perfectly centered, nor is it straight, but at least it holds the ship up off the floor, which is all I needed.
I decided to forego making a Terran Empire logo base, mostly because of the time and effort involved. You won't see the base in the pictures, so it's really not worth the effort.
