This is simply stunning. The cold color tone is amazingly right for this shot, and if I didn't know this was a photo of a snail on a flower, I would have just thought it was some abstract 3d render or something and loved it anyway!
The crop seems a bit off to me, I don't know exactly what I would have done differently, but it seems like it is upside down. Or maybe I would have cropped it a bit narrower and taken of a bit of the right side. Just tiny things really, and it is a matter of personal taste. There is really no right or wrong when it comes to art.
