I concur with Corsair's assessment. In particular, bulkhead 4 seems to need a lot of work. Also, the other bulkheads could stand to get evened up close to the false keel.
In my limited experience, fairing bulkheads seems to be a never-ending task. Once you think you've taken off enough, there's still more to do. Endless iterations of sand--check--more sanding--re-check. But the time spent will be frustration saved when the planking starts.
