Too much is out of focus, making it look like the picture is a victim of Bulls'-eye syndrome. The unfocused yellow at the bottom also draws away the viewer's eye. A good cropping of that bottom stuff would be good. The focus on the flowers you DO have focused though is really nice. Red placed against blue makes them vibrate against each other but that's what's making the picture so vivid; it would be much more powerful without that yellow.
Lots of floral shots on this site. This one stands out to me. I think it is the vertical orientation and the overall composition. Almost like an explosion. The only minus I can see is an odd halo around some of the background flowers. I added this to my faves.
Nice shot, but i wish the yellowish grassy stuff wasn't at the bottom of the photo in the background and I wish you didn't get so much sky because those two things add extra colors. But great shot anyways! good luck!
