Something suggests to me that you yourself liked your last one here best, joyride? It could be the frame that indicates it, maybe
Well. The last one is the best of the bunch! Not that I would know what it is I am looking at ... but I like the lines and shapes of the areas and the colours and contrasts and light.
I would also like the first very much, for the same reasons as Gimp is giving, only does me bug the fact that the seams between the stones are somewhat distorted so that only the bottom seam could be aligned with the frame, but the top one could not. I am sure this is something beyond anything you can influence, but it puts a bit of a damper on Photo 1 for me...
