I don't even know where to start with this picture. It's out of this world. The colors look so unreal - in a good way, mind you - they just leave you wondering how on earth something like this is possible.
Needless to say roses as well as drops make awesome subjects in photography, and you combined the two wonderfully here. But I have to come back to the colors, coz they simply make this shot unique.
The focus is spot on, the details are amazing, and the framing is very well chosen. Good job, this is a really outstanding photograph of a rather common subject!
