Hi captain,
It's a nice cabin, and quite spacious; which leads me to wonder why not have it more decorated; a chest, or any brick-built furniture like a dresser would give it a better look.
The construction/shape is good (taking into account that you do not have a huge stock of parts if I understood correctly).
Regarding the rigging that you plan to get, I would advise you to take the longest version in priority if you dont already have some. The shortest are useful for the top of the masts, or on a smaller ship like the 6271 Imperial Flagship.
Maybe it's just a personal taste but look for pictures before purchasing anything to get the final appearance that you like the most.
Also, the building has something a bit inconsistent.
You have covered the floor of the cabin with smooth tiles (a finishing technique), but an element that is seen at first glance from the outside; the edge of the red roofs; is left with apparent studs.
There it requires a finish, not especially tiles but.. something.
You use golden telescopes to make a rail, then a brown grid to do the others, and an (actually pretty interesting) technique with the rope for another. You understood the idea.
I hope I did not offend you, that's not my intention. Only trading skills between one ship builder an another : )
As modest as they are compared to the monsters that navigate the forum, your past ships always have a little something unique and I will follow you to see this new iteration of the Queen Catherine's Revenge.
