56dOk, after receiving some very helpful tips I have rebuilt the main gun deck with each gun 3 studs apart.
I don't know why I never tried this before--even after I saw numerous ships on Brickshelf with at least 3 studs. It looks so much better--more flowing i guess you could say.
I've also added cat heads and anchors (a detail I've been meaning to add). I also removed the lowest spar on each mast, and I'm replacing them with just lines. It's more detailed that way, and I get extra spar parts.




Thanks a bunch for the advice everyone. More ships coming soon!
P.S sorry for the image size, I'm technologically challenged so I don't know how to down size them.
