Just bear in mind that all around the edges, a "box" has to be built on which the strengthening part (verschansing) of the bulwarks (fortuining) comes later. For this deck, I did not remove the frames (spanten) but did plank right to the edge as you did. Afterwards I had to remove those planks again - so it was double work.

Here you can see the "Black box" I was referring to.
Then I learnt my lesson (see the picture of the forecastle deck where you can clearly see the unplanked edge where the verschansing will goes.

Another random thought while I'm here now. Make sure that the bulwarks markings on the bulkheads are clearly visible. I marked my lines on both sides so that they could be visible from the front and back. Those lines are worth their weight in gold when it comes to planking this hull.
Now back to your deck: It looks great! The steel wool vinegar solution certainly does the trick - I was too scared to try that!
