I think it looks pretty good :)

You can change the colour of the cliffs using either an Adjust Hue/Saturation or Colorize sheet effect on that sheet. While these effects don't normally work with symbols they will with the cliffs because the cliffs have map files.

You might need to do all those split level differences on the deck with a separate set of sheets for each one, so that you can cause the upper ones to cast a shadow or a dark glow over the lower ones. You've got 3 levels, as far as I can see. The highest one is the stern, or aft deck (and now we are going to see if I can remember all the terminology!). The next level down is the mid and fore deck, and the lowest level between them is... ummm. I've run out of terms, but that's kind of a mid deck also! LOL! And its about the same level as the bow, so you could put them on the same set of deck sheets as well.

I'm not sure how that would translate as far as the general outline goes, but if there's a step up or down in the deck level, then there will also be a step up or down in the freeboard. The bit that sticks up above the water line. So you could draw it as 4 separate decks (on different sets of sheets) that just happen to make the shape of a ship.

I think you might find that the part of the plan view not shown as planked down the sides is the bulge of the lower decks, which if you look at the stern elevation plan stick out beyond the extent of the deck. If you look at where the gun ports are located in all the plans you will suddenly see what I mean. The true extent of the deck is where you have drawn the paler planking. The extra extent should be very steep flanks with the guns poking out of them.

Another way is to hold down both the CTRL and SHIFT keys at the same time. The disadvantage of using them together like that is that its very easy to press only the CTRL key for a split second before you hit the SHIFT key, which makes it easy to accidentally scale the label instead of rotating it.

Cities come in all shapes and sizes. I suppose realism is down to where you put the city centre and all the important and functional buildings.

Have you made your new symbol catalogue?

If you have, and until Remy responds on the settings thing (which I never use), you can open any catalogue you like just by hitting the folder button at the top of the symbol panel. Be sure to open the catalogue file, though, not the actual folder with the images in it.

Catalogue files are .FSC files.
