Progress on a large project such as this one always takes a lot of time. From what I see you're doing marvelous building here.
On a light note, I noticed that in your post back in October your little tug really gets around! . What kit are you going to use for the tug or is it scratch built? I used a nice little kit back when I did a Liberty Ship for a friend of mine. See here:

Twenty years difference though. I wonder what tug kits are available in 1/350 for your carrier?
