Unusual combination of subjects makes this an interesting shot for me. Not sure I like the border though. Have to come back for another look later to decide.
The leafes are nice and sharp, but I think I'd change the PoV a bit. the main subject of your entry isn't the glass anymore I think. But that might be the way you wanted it. I don't really like the border.
Really pretty coloring on the prism. Why did you put a line around the image? It is well detailed and exposed, but the line bothers me. If you were trying to create a beveled look, I think that it might make for a great creative use of editing, but since it can't be done in basic, I would have left the line out. 7
The exposure is dead on to me, and I like the violet hues in the crystal. Not fond of the internal single line border - it's not needed here - picture can stand alone without it.
Sorry but the frame almost made me deduct a point, it really bothers me somehow but like I said, I tried ignoring it for voting purpouses, after all, it´s a photo challenge, not a frame challenge :)
I really like this shot for it´s stunning image quality, very sharp and the purple crystal contrast very well against the green leafs. Nice work, 7 from me.
Its hard to pick out why I dont quite like this. i think the leaf looks possibly oversharped. im not sure though, but I do know the border seems way too thin. Its also composed a little too centered.
