Hey, that's pretty cool.
It'd be fun to make a physical model based on that layout. I like the fact that it's made up of large basic shapes with just a little panache here and there. The general layout is very indicative of the ship design styling they used for the original show.
In fact, it has a little whiff of the Asrosleds they used in the "Fighting 49th" episode of Buck Rogers... which is a GOOD thing. I liked thse ships.
Honestly, I think you've tapped into the flow... the mindset of the guys working on the original show. Good work.
A few kitbashed details and some apprpriate armor hull plating (be sure to add the red/orange stripes!) and you've got yourself a first-class Colonial Bomber.
Unless, of course, that WASN'T what you were going for. In that case, just ignore me... i'm seeing things where they shouldn't be.
