This is a great photo. The contrast of the colours is classic. Also the sharpness of the foreground flower is tops. A very pleasant and pleasing photograph. Good work.
I really like the colors - they are very pleasing. The only constructive criticism I might add is that, IMO, I think the picture would be better if the composition were changed so that the stem of the main flower in the picture weren't cut off so close to the flower itself. That looks a little awkward to me, but I really think this has a lot of potential.
Excellent colors and the blue backgound really makes your flower stand out. Only one thing could have improved it even more if you had cropped a little tighter to your yellow flower thus getting rid of distractions in the left of the frame. Very good picture and pleasing to look at.
Everyone say's that love makes the world go 'round, but come'on, everyone knows what makes the world go 'round is really a mutant gerbil on a treadmill.
