The main reason I was unsure about writing a critique about the picture was that I didn't know where to start. But, I'm here now, so I will have to start somewhere.
This will be the main thing in focus. I can't quite tell what it is, but it looks like some kind of plant. With spikes on the top. I think. This is the reason you have got 3.5 stars on technique. Although it is a nice picture (as testament to the 5 stars in impact) I cant tell what it is, even though this was the intention, due to it's abstract and surreal grouping.
Whatever it is of though, the picture was taken superbly. the lighting makes the plant look almost magical, as though it glowing with some unearthly power. I just want to take it from the screen (something which is also helped by your amazing picture quality of the camera used).
The background being out of focus bring even more attention to the thing that is focus, which is the plant I have mentioned before.
Overall, even though I dont know what it is of, it is still an amazing picture.
