with all due respecs, eswube, there is no reason to be that harsh on this new member. there are already some improvements in this new drawing other then the colour, and the basic layout of modern warships is there now, while there were a lot more issues with the previous one.
the dimensions and the systems are still of, yes, but apart from the exact use of the radars we have here an ship that could work by moving some stuff around.
2 hours is not a lot of time to spend on a shipbucket drawing, however I have in the past done ship designs fit for construction in 8 hours. I think everyone will agree with me that getting everything exactly right and researching if everything works takes most of the time involved in shipbucket drawings.
the guide eswube posted in the previous thread and the ships in the archive give a lot of information on how ships are laid out and shaped. however, the step every artist needs to master on their own is the how and why. the description eswube offers here (center of gravity as low as possible) is a benchmark, but only for submerged submarines entirely true
hexel, may I suggest you take an example ship (for example an real life destroyer or frigate, your current setup is not far off from the latest european ships except for the single propeller) and study their how and why? try to find out what kind of weapons, radars, propulsion etc they have and what effects those have on the ships size, speed, shape and setup. try drawing a real life ship to master this or draw your own version of the ship you studied earlier.
in addition, maybe best to stay away a bit from the old parts sheets section but instead look at the more recent parts sheets, those are labeled better, sorted better and more accurately drawn
