it's quite noisy so you must have had to bump up the exposure a bit in postprocessing? It's a beautiful shade, but perhaps try making the focal point the front petals and letting the rear ones recede? The stamens aren't at all white, so I'm guessing you were pushing the color quite a bit? Not sure. It's still a really pretty shot. I'd just run it thru Noise Ninja or whatever and maybe just tone down the saturation a bit--it's dangerously close to posterizing.
