They don't call me squinty for nuthin!:grin:
Some interesting things come out of the overlay you did...
I noticed the forward house has a slight rake, which I didn't notice from the photos...and probably is not as pronounced in the plans, but looking at the overlay, there is, indeed, a slight rake, rather than a straight, plumb, front.
The after gun seems to be located a bit further aft in that schematic than what the plans...and your design...show. I would go with the plans over the schematic on this...but check out the photos to be sure. Look at this overhead view:

I think the plans are more accurate than the schematic.
And take a look at the forward edge of the foremast...it is apparently more square than I originally thought...whereas you can see the after rake is more extreme on the after mast...and not as wide going fore and aft. The lighter areas of your overlay extend a bit beyond the schematic shows in the front, but the lower end of the after mast ends further aft than your overlay.
A very interesting technique to check the lines, shapes and arrangements, eh? Good one, mate!
Glad the color swatches are helpful...I had a bit of trouble figuring out exactly what colors relate to what part of the ship, but perhaps the photos show the different shades between the sides and the top sides, particularly in the photo taken from above.
Whew, this is a lot of work, isn't it?:grin: My admiration for what you and other designers do to make these models is always increasing, that's for sure.
Cheers!
