Thanks for the really kind comments everyone
At first I wasn't pleased on my first 'cull', and kept going through them every few hours, reorganising and prioritising them.
Eventually got round to processing them.
I agree with the oversharpened bit, and it's really annoying me.
I have only done very slight sharpening to the 700px shots I saved, which I then uploaded to flickr.
Flickr then, in its infinite wisdom when it resizes to the 500px preview you see, it sharpens them some more.
So I upload undersharpened shots, and it resizes and over sharpens them...lol Seems I can't win
Once again, thanks for the comments
