1 was almost cool, for me. I wonder if the space in between the shadows was light only, if that would have helped. Most likely out of your control as they are probly shadows of trees or something. but defined light vs dark in solids/lines prlby would have made that work for me.
2 not diggin it. just not into the whole pic being blurry, in any photo really.
3 again..almost worked, but less than 1. too much OOF/Blurred areas for me, it kinda confuses me and I find my eyes all over the picture trying to figure out where the focal point is and what to focus on...then I get dizzy. Probly a cool thing...who knows...just not workin for me. I wonder if either the stripes were in focus and the circle blurry, or the circle in focus and the stripes blurry, if that would have made it work. A little of each blurry and not. eh.
