The daylight makes interesting effects in cut glass.

An abstract photo like this is just begging to be played with in post processing. I really like the square crop, but the central vertical line isn't quite vertical, and there is some perspective distortion which is easy to correct.

I'd also try to drop as much of the green as possible (is the white balance correct?)

Here's an attempt at a quick edit, doing the above and boosting saturation. Not much different really, now that I look at the two side-by-side.

Nice subject. I would love to see it perfectly centered and symmetric, though. It could be a little bit sharper too.
