Sorry -- it's another one that just looks underexposed instead of low key. If you would have kept it in color and exposed it right with some cool side lighting, it could have been stunning, imo.
Hmmm.... this is such a hard topic for me to comment on... not really understanding it completely.
But, I will say that I didn't know what this was until I read your title. It might be just a bit too dark and... in my opinion, the reflection just confuses me. I think it would have been a really lovely image with just one blueberry sitting lonely on the bottom right thirds intersection and just a tad bit brighter to really catch the viewer's eyes right off.
Take that as only one person's opinion (who most likely doesn't know what she's talking about. *grin* )
I have viewed this on three different screens - an i-pad, my calibrated home computer, and my un-calibrated work monitor. On my ipad and work monitor, the black overwhelms to the point that there is only an unintelligible smudge of light. On my home monitor, I can just make out the blueberry and its reflection, but it requires too much work from me as a viewer.
