The first is a perfectly pleasant panorama but doesn't seem to have any particular purpose to it.
The second looks unreal to me. Is it HDR? There seems to be far too much light on the rocks, given the position of the sun.
The third, I like a lot. The small stone in the foreground makes it.
The fourth has lovely light.
I agree with Jeremy - the first image seems a little flat. The second image, not so sure, but I do like the last two.
Thank you for the feedback, really appreciated.
Point taken with the first. When I reached the summit of Quinag to take the shot the wind was very strong as a storm front was approaching, heavy rain and 80mph winds. As a result, it was camera out, grab a shot and off. The light was not at it's best for sure.
The second is a straight shot. 2 ND Grads stacked, a 2 & 3 stop. Not into HDR etc so no tinkerings in that sense so who knows :-) arrived just in the nick of time before it the sun disappeared.
The last two were more controlled shots and by that I mean I had been sitting around for a while waiting for the right moment etc and I guess as a result are less forced, if you see what I mean.
Thanks again, I find the feedback very useful in the overall learning process!
