Part of the flower is soft because you have used a relatively long focal length (70mm) and been pretty close to the subject and a relatively large aperture of f5.6 (1/640th sec shutter speed).
You could have stopped down to f8 and perhaps stood back a litte (using a slightly longer focal length). this would have got more of the flower in focus (if that's what you wanted).
That's exactly what i wanted. Thanks a lot for the feedback. That flower hasn't gone anywhere so im gonna try and take it again using those tips. Thanks a lot
Ok i went back and tried again, this time using more depth of field. I'm using the kit lens that came with my alpha so 70mm is the best i can do there. I think this one does look sharper though.
