Just love how the light enters the image from the very top. The eye is led to the retreating foot, an afterthought, leaving an expanse to investigate and explore.
As silhouettes go, this is beautifully understated. It's like essence of silhouette, distilled and sparingly applied for maximum effect. Fabulous image, 10 from me. (The vote was in long ago, just commenting now)
Love the shine off the tile and the distance portrayed. Huge eye draw to nothing, and then you follow the other path - to the right, and notice the open door, and the back of shoes. Definite feel of mystery and curiosity as to what is going on. Nicely done.
Even though the strong leading lines and bright spot on the left are so prominent, my eye still gets stuck on that one foot, making me wish I could see more. That must mean something good for the photo. I think I might have cropped a bit from the bottom though.
I also just realized that you received my 1000th comment. Congrats : )
