I like to see another ship here on this forum, fore I build one too here in WiP section.
https://blenderartists.org/t/uss-bonhomme-richard-1765/
Yours is in more developed stage and I can see 3 problems (i don’t know whether you meant it the way)
- deformation in the front
- deformation in the back
- too rounded cannon holes (but I’ve seen a few like this in real life (but they are not just holes then, they have decorations there))
Good luck tho, and I will be gladly checking out this thread again.
