I love this shot. You were able to focus solely on the rose and fade out the background (stem, rain). I love the raindrops that are splashing off of the rose. That helps it look as if we are there with the picture. The raindrops that are directly in front of the rose are a bit distracting, however. They make the viewer lose some focus on the flower. But, I do understand the fact that this is a fast moving scene. The only suggestion is try to speed up the shutter so maybe the raindrops in front have a bit of focus, too.
Though, the drops DO give the picture more motion to it... Hmm. I think the picture still looks good without the focused rain drops. Overall, this picture is beautiful and relaxing. I swear I can smell the rain and rose right here with me!
