Wow, I love what you photographed! The colours go together very nicely and the ensemble looks good. In talking about the subject, I would say that taking a macro picture of something that has imperfections is not flattering to it. But it is a great way to see up close and in great detail.
It is a very original piece, in my opinion. Having the photo taken with other pairs of earrings next to the main subject makes it look separate from the usual commercial photos that say 'buy this pretty and shiny thing.'.
I like how only the subject is clear, for the most part, as it attracts attention to it. However, it would have been better to focus more in-between the two blue earrings. In this way, both would be more clear, and the metalwork of the green one would have been more blurred.
In my opinion, this photograph is very interesting. When I first say it from farther away I thought it was colourful bottles and went in to have a closer look. I think that is has quite an impact on the viewer, though it would be more stunning if both blue earrings were clear.
Overall, it is a great photo! And the earrings are pretty too
