ive moddified mine, adding an extra boat hull from my viking ships moveing, the rear mast 1 brick higher, spreading out the cannon ports, removeing the swive gun for use in my fort, a row boat hung on the back of the quater deck, a change of captain,diffrent flag, diffrent lantarns and a whole lot of other stuff.
i still have plans to change stuff, makeing the deck higher so that the minifigures dont have to bend over, changeing the crane and small modifications like adding more gold.
i would like lego to realish a nice two deck ship for the imperials.
id change the row boat on yours to a brown one, and the number of cannons would be impractical since you would need a lot of crew to man them all
the cannons would also be heavy makeing the ship slow.
ive got 9 crewing my ships but i plan to add more to the ranks, preferably doubleing the current number(viking torsos and random hair pieces will help me achive this number).
its a nice ship that could benefit from an extra ship hull piece.
