Just a reminder to keep a firm eye on the composition and not get too carried away with obtaining the effect of PP tools.. Without composition a well processed photo is still a badly composed photo. The best is still to have a good composition, processing can always be redone if you get it wrong.
It is usually not such a good idea to chop parts of rocks off unless it is clear that you don't have a choice. For #152 I am wondering why you did not go for a horizontal composition and try to go lower and to the right with plans to clone that stray rock on the right away if you couldn't crop it out. It is a bit tight on left and right side.
#153, bottom rocks are also abruptly chopped for me. My suggestion here would be to go in front more and try to form a leading line with the two smaller rocks in the distance and the big foreground rock.
Try to take note that your sky shouldn't be darker than any other part of the picture, as it is the source of all light, where the sun is... #152 is fine, but for #153 the reflections of the sky are brighter than it, and so is the whole chunk of foreground rock..
