I think your flower stands out original. The dots are wonderful they add a spice to the wholesome view and the lighting with the contrast in color oh well that is just my thought.
This is so richly textured in your post-processing! Love the effect! It seems it has enough contrast to carry off this technique. The blue of the flower(?) next to it is a nice contrast, but I think the green in the corner detracts. Nice, overall.
ISO 1600+? Looks like the shoot was way too dark, then you used levels to bring light from darkness, so noise is extreme, more than a correct exposure under ISO 6000! But the effect, even if it was not intended, is nice, like puntillism (the noise is of "good quality" if you understand me)
I like the image. The comp is good but possibly a bit too centered. Colors are great. The image seems a little noisy to me. Could you clean it up with Neat Image or some such? I actually like he noise on the petals but the noise on the blue is a bit distracting. Another possibility would be to trim a bit off the left ... eliminate the blue and adjust the over centered comp all in one go. Still a beautiful image and worthy of recognition. Good luck.
Sorry, the tight DOF and grain don't work for me on this shot. Seems the center of the flower should be in focus as well. Everything looks like it was splattered with paint.
