ND filter would improve this image?
imo probably not, I have a 8ND and recently whening using it at Bare island I found it was a struggle to get longer shutters required for 'silky water' when the sun was up there around 9-10am. I think the sharp crisp approach was the right one here jon. Incidently, you can see Bare island from your shot
Maybe getting there a bit earlier my be of help, even sunrise? but that hurts...

its a fair drive around to that point.
Did you get around to the 'seaside' of Kurnell? there are some nice walks around there from memory, I have not been there for years...
Also, you can pickup the stitching seam leading from Bare island to the foreground of the picture. It is quite difficult to stitch panos with waves in the foreground.
hth.
I think we should allow more than 800 pixels for panos.
I am a big fan of the 800px, there is nothing worse then browsing a forum and popping out half a dozen threads into tabs to have it lockup with a couple of the posts with 4 odd 300 Kb each - especially when on a laptop with wireless speed.
