Hi Joe,
I have now added a link to this 2nd Quarter thread from the 2016 P52 Index page, along with a couple of other member's ones I had missed.
OK, going back to the Washington Monument, I am in complete agreement with Judith; good job on sky, but I feel it is too 'centred' (left-right).
With the pedestrian walkway shot, I find the bit of canal gates we see as a distraction and I'd crop that off, just leaving the trees and the curved wall - this places the walkway in a better position within the frame I feel.
In the last shot, of the gates, that's fairly OK, although it is a shame we cannot see the end of the gate beam on the right hand side, however, I accept that including that might have brought something far worse in to view.
Moving on to the latest picture post; I'd be happier with the wider view if the woman was just a bit further left in the composition - unfortunately, I suspect this was something you couldn't improve even by moving a bit further to your right (if that were even possible) and still retain the framing of those trees.
On the closer composition; again, I'd like her a bit closer to the left edge of frame. I'm also not a huge vignette fan and find the whiteness over the rocks mid-left edge is off-putting. I can fix both issues to my satisfaction by simply cropping at the lowest point of the V-shape formed by the rocks and water, but not everyone will agree with me and that's fine.
I quite like the idea of shooting with a view to finding another crop within the frame, it is kind of reminiscent of taking the scene as you first see it, then showing the final image after 'all things have been considered'.
HTH, Dave
