With such "radical" processing, any kind of "technical" suggestions are really more revealing of taste than anything else.
Personally I really like your edits - there is an interesting vintage/grunge feel to them that would fit well on a poster for a horror-movie or an early Balck Sabbath album..lol. And you are clearly not trying to maintain a "photo-realistic" perspective, but a rather artistic interpretation.
I strongly suspect that these images would be a lot more powerful in large prints. These thumbnails we are looking at, are obviously not doing them justice. Subtleties are lost.
My personal favorite is the one with all the pillars, primarily because it's the composition that is the most "unusual" of them all.
Given your obvious talent in post-processing, you might ask yourself: how well do these compositions stand on their own - i.e. are they "strong" pictures without the grungification, texturization, noisification etc. If you did a more "traditional" edit of them..color, sharpness, contrast..that sort of thing, how powerful would they be? Are the images given their impact mostly or even purely by the edits?
I don't have the answer and taste vary hugely - but you could perhaps explore that line of thinking to guide you to images that you might find are even more compelling.
The "binoculars on beach" shot: I have this thing about deliberately tilting the horizons, which are very much in vogue these days - and my opinion is: do it like you mean it, so there is no doubt that it's done on purpose. This image - for me - is on the edge of that..lol. But that's just me.
I can only guess at whether it's deliberate or if it's unconscious on your part, but this series has a tendency toward centered symmetry - your horizons are in the middle on many of them. I'm not evangelist when it comes to the "rule of thirds", but I imagine that a few of them might come across even stronger if you had dropped to your knees and dipped the horizon up or down on one or two of them.
Thank you for a very enjoyable view of some very artistic images that clearly took a lot of very deliberate work on your part. I greatly enjoy them and I imagine that they will be well received on 1X - even if they are rather particular about the shots they allow on their site.
