I'm sorry, but without any input from you in technical details or comments, it's just not possible to critique this image.
When we do a critique, we go past just the photographic result, that's what voters comments do. The critique looks at what you were trying to achieve, how you wanted it to look and what issues you had in getting the image captured and ready for voting.
Some hints for the future:
==============Composition ==============
Composition is about leading the eye into an image (painting or photo). Research shows that the eye enters bottom left and travels up to top right ("Leading Lines Rule"). Once in there, the same research tells us that the eye finds comfort when the point of interest (POI) sits on a thirds line or intersection ("the Rule of Thirds").
This meets the challenge. However as an improvement, I would locate the main burst of color in either of the sides as opposed to a centrally placed subject.
*I am only commenting, and not voting on this challenge*
Pretty flowers, and nice color play, but lacking that fine detail touch (especially with sharpness and compositional play), that a good DPC photo needs. Try playing with your angles and DOF some more, and get more creative, while having fun.
3 - Using one or the other of these two different colored pansies would have made this better in my opinion, as well as a different perspective/angle and composition.
I love the colour...perhaps the sunlight is too strong casting very dark shadows...some fill in flash with some compensation as well as a reflector could have lifted this
