Let's face it. the Camara looks like a hunk of junk that's badly textured, and needs a facelift.
I'm a hobbyist concept artist that happens to love spaceships, so naturally I've been feeling for some time now about giving this (and potentially other ships) a facelift.
I have to leave for work soon, but when I get home I'll continue more than just a thumbnail.
In the meantime, run around on my tumblr and artstation and feel free to drop a comment.
And now, I present to you, a 5 minute thumbnail sketch!
In any case, I think you should keep it as close to the current shape as possible. It has a reason to be flat and "cylindric". It was designed to run through asteroid fields. So, having those up and/or down 'protuberances' will be a trouble for that intent.
