Well, this is a really nice flower photo with excellent lighting. As you stated this photo type has been done before, but you are doing a great job with the subject. This photo is not breaking any ground, but a solid shot none the less.

My one suggestion would be to crop the right side to match the left...the flower does not seem to be centered and in this photo I think that would help.

Great job, and will be looking forward to more.

Cheers.
