Here's one of the pics - and link to all 6 in gallery - from the end of a day on north Somerset coast; my first outing with ND grads.
In terms of what I was aiming for, it was to capture some of the beauty and quiet solitude of that setting, while 'getting' and experimenting with water effects from slow shutter speeds I've seen others achieve.

I was pleased with these when I got back to the pub and looked at them on my laptop. This might be my favourite from the set, but that keeps changing... and there are things I like better about others in the set (the scale / size of the posts, reflections), though I like the rocks and the water effects - both the waves behind the posts and the swirls / patterns at right - in this one. Probably can't have all in one pic.
Exposure times here range from 0.8 to 6 seconds, and I've pushed the ISO up to 3200 for some of them, which I'll avoid if possible next time.
There are other things I think could be better.
For example, in terms of composition my position was a bit limited by the tide coming in and not wanting to get soaked..! When I go back I think having the 3 sets of posts closer so they occupy more of the right side of the frame while retaining foreground rocks in frame and the cliffs on the left with some sky above would be good. I'll try to time it so the tide's highest just before sunset next time.
Oh, and the horizons could be level... I know I could crop to achieve that, but I tried and it loses the sky above the cliffs to the left so I decided not to do that
I really want to know more about the effect of using different amounts of ND grads. I didn't have time to experiment with changing the amount of grads here. I took meter readings off the sky and the foreground: there seemed to be so much difference, that I just put the two- and three-stop hard edge ND grads on that I have.
So, from the results: did I 'over-grad'..? If I did, what gives that away? What difference would less ND grads make and how would they improve the pictures (if they would)?
Are there other things which more experienced members here would do differently?
In terms of how robust I'd like (and can take) any criticism to be - picking up on Robin's point, here - I'll try to imagine we're having a few drinks down the pub, and you're looking at these with the aim of telling me what I'd need to do to correct any technical and composition issues, and to improve on them to make the next ones really outstanding. To that end, I'd like to think I could take some fairly robust, well meant critique..!
I'm planning another trip there next week, weather permitting, so hope to have more to post after that.
