as you got in the PM:
- doors
- hatch
- ventilation
- pipes
- moorings
- caskets and rollers/drums for storage of ropes on deck.
- fire hose
- lifeboats
- commander boats
- personnel boats
- shading
- support to overhang. for example on funnel
- wires from mast, some of them are VHF wires/antennas
- radar of that time period
- spotting top
- binoculars
- props
- spread windows a bit more out. (Think on where you think crew compartments are, mess halls, etc. areas that need windows. But engine room and magazine don't need any window.)
- where are the coolant water to the powerplant coming from...
- where are the coolant water coming out. (often some openings above water line.
- hull depth markings, and other type of markings.
- class Number (like BB56 or BC48 etc.)
- small signal and spotting light.
- large spotting lights.
- bridge wings.
- oh remember to have 18 px deck height for full deck height. at the moment. your bridge/conning tower looks like its only 7-8 px heigh! (tips. mark bridge height with an line of an different color that you can remove later.
- and many more.
- note. conning tower, on the big one. why have windows 3-4 px from each other in height. No ships in the world have that. (Remember the conning tower is to protect the admiral, to many window ...)
