I like the use of black & white for your image. I also like the texture of the dried clay on the hands and I get a sense of the wheel motion when I look at your photo. Well done and good luck in the challenge.
Still Life - Inanimate object purposely arranged to emphasize texture, color and composition.
Still Life - Anything that does not move or is dead such as cut flowers, fruit, food, wine and so on
Lovely photo which I quite like. Tones are pleasing. Shapes and composition are very good. Focus is excellant. And if that werren't enough, I simply like looking at it. Sadly, it is not IMO a still life and therefore fails to meet the challenge.
