This is the build I'm usually working on via my passworded server. It's around 35 thousand bricks so far, and is around... a bit more than half done! This is a GIGANTIC battle cruiser. Take a look:

I started on the project about 4 months ago. However, I've taken many little breaks in between, so I'm not sure how long I've been working on it, exactly. In case you're wondering, the ship's not going to be a boring tube shape, like it is now. It will have a shorter, thinner tube coming out of a wall where that gap is, leading to a command center shaped like a sideways dome. I'll also be adding cannons and guns of all sorts around the hull. (I know that the current shape is dull and boring) I'm also going to try and add a place somewhere inside the ship for fighter pilots to launch into space, if my computer permits vehicles in this mess.
Tips? Opinions? I hope you like it so far!
PS: Sorry about the way I posted the pictures. I couldn't figure out a better way.
