Launch Tube - work in progress Pt 2

Thought I'd do an hour or so on my spaceship launch tube that I started here Launch Tube - work in progress
Added some detail around the mid area and bay doors.

Launch Tube - work in progress

I started this a day or so ago. When complete it's going to be the launch tube for my Orange Spaceship. Again I loved all that late 70's early 80's Sci-Fi like Battlestar Galactica and Buck Rogers in the 25th Century where we seen spaceships launched or flying down launch tunnels etc... Not too sure which way the bay doors will open when I add them or if the bay needs any doors, any suggestions would be appreciated. Still got a lot of work to add to this. There's a small control room in the bottom picture that'll be illuminated. I suppose this section is a small area of a larger ship or space station.
Oh yeah still not 100% sure about the size of this ship to a person, at the moment it's bigger than a fighter, more of a 2 or 3 man ship though I think in the final scene the ship will be around 20 -30% smaller than seen here.
Cheers for looking.

I've taken the You Tube video down that I posted as it was very dark and didn't really do the job it was intended to do. I'll post a new one once more work is done.
