Maybe this will help a bit.
I've recolored lines for emphasis, removed shadowing, etc. to focus on structures.
You're almost there. I think what's needed is a bit of fairing/tapering toward the bow of the lines to make smooth and graceful "lines". Back in the day, they had a strong artistic bent on ships. They were functional art.
I also seem to recall that either in the Forum or maybe in the finished/submitted drawings there is an HMS Victory. Try a search for that one. It may help a bit.
Off to work.
