I looked at this yesterday and I can't figure it out, I like it but I can't say why. I keep looking around and I know what I'm seeing and the black areas look wrong but work for me somehow so there you have it! I like it and I don't know why!
Interesting, but looks a little flat to me. I'd try darkening the mid-tones some, mainly to darken the dirt and make everything else stand out a bit more.
For me it a very strong feel of scanning electron microscopy to it. So strong that even though I see the flowers and the rocks, part of my mind is working hard to determine what type of cell I'm looking at. I think like it. I've definitely been staring at it for a while. Must try to break away!
