Very nice, handsome little ship that is.
I disagree with the way you've shaded but not knowing what the hull shapes are, I cannot really say what would be a better way to shade this.
This is a very interesting question, I have no idea actually since my only colour reference were pictures of a model from an arsenal, which had very aged wood for obvious reasons. It'd be interesting if somebody knew.
Tremendous!
Isn't the camouflage applied too perfectly, specially over the boats?
I don't agree with the shading method you've used but it's very well drawn.
