It's certainly much better, as the edges look a lot smoother
However, you still have the central part of the platform with a lower width than the deck
--->There should be NO gap at all! Can you make it wider so they both match?
The other point that would need a bit of attention is the hull curvature around the point where the platform meets the hull, as it needs also smoothinga nd looking more like an inverted cone BUT don't touch the gun platform, it's the hull what needs to be tweaked!! The gun platform is correct now, with a vertical wall.
EDITED: The rear gun platform looks already very good, just tweak the hulla round the forward one to make both look the same.
Almost there!!!!
