Seriously, I'm not good with curved or straight lines. So don't get upset if your lines are a little crooked. Go ahead and add detail to the smoke stacks, deck, superstructure (the higher level above the deck, bridge (the small structure in front of the smokestack, but on top of the superstructure). Make sure you get those portals (windows). Draw a straight line with the ruler for the bow (front part of ship). Please don't feel I'm talking down to you because it was challenging for me. To say the least, I'm helping myself to remember those ship parts.
