Interesteing pattern, repetition. I like the bright pink contrast with the scratchy silver.In spots the lighting is a bit blow out, and the focus isn't as sharp as I'd like.
The nuts form an interesting pattern, and the metallic texture is well captured. I think a plain white, black or grey background would work better than the vivid color you have.
Love the background colors. I think the focus of the shot is a little bit soft and the crop seems tilted--- I'm think that this object might of been round? It was a good idea for the challenge.
