Two things, Rob. First of all I was always taught that centering the subject is the last best alternative. Translating, that indicates that offsetting the rose might have increased the overall interest in the image. Secondly I too like the soft focus although it seem to lean a little too much towards soft and less towards focus. That being said, this is a better flower shot than anything I ever hope to post.
Rob - Your new camera is a keeper (especially since its already paid for) as it is providing you with some good 'stuff'. Outstanding lighting, especially with the shadows hiding all but the bloom and a bud and few leaves. I agree with Roger's comment that the bloom focus is a bit too soft. However, that gives it a velvety smooth texture. Thad
