It's quite nice start. I don't see any big problems with it.
Just some excess of black (double black lines) in some places - on the mainmast, where the vertical pole meets the slanted one (neat the bottom of the crow's nest) and around davits (overlapping with boats - their keels don't need to be separated from the rest of the boat with black line - dark contour of appropriate shade suffices), maybe in one or two other places.
Perhaps some minor details could be added (more cleats and bitts, capstans etc. etc.).
But otherwise a quite good work for a first attempt.
