I find the colors pleasingly arranged. There are so many differing points of light that it's hard for me to get a handle on exactly the position of the source, but I guess in this case, in this genre, it's not important.
Michael, I like The Rocked Shore - it's rocky alright, which is a texture unto itself. Your enhancements strike me as complementary to that foundation; the "X" lines on the large rock on the RH side of the frame imposes a "manufactured" feel over the rock's shape. The reddish colors seem to infer rust, and the "god beam" gives one a feeling that these rocks have more intelligent orgin than just rocks...I like this picture because in these examples, it gives me a lot to think about.
The color palette is good and the oranges are warm and pleasing. However, there seems to be a great deal of conflict between raw, straight lines and curves--it needs more thought to the natural process of erosion. The small rocks around the base of the larger ones should be smoother and more eroded than the large rocks. The straight-edged squares and rectangles on the large rocks should be softened (where convex) or cut more deeply (where concave). If you mean it to look as though erosion hasn't had much time to work, then the top edge of the large rock in the background should be as sharp as the tiny rocks. But overall, negative and positive space are balanced, the color palette is good and the sky gives it a nice otherwordly feel.
