Hmmm... this is a very intriguing image indeed! I've looked at this image for quite awhile, and a have a few suggestions to make.
First is the background. In the two bottom corners, your sky is yellow. Above that, it turns directly to blue. The idea of a transition is FABULOUS, and really brings a lot to an image, but right now it kinda looks like you forgot to change the tone on the lower half. I would suggest maybe waiting to transition until 1/3rd of the way down, instead of 1/4th, just to get a few extra colors in there.
Also, the differences in sharpness throw me off a bit. Your blade of grass and dew at the bottom is very sharp and very visible. However, your flowers don't follow suit. They seem a bit grainy and overly sharpened. Perhaps smoothing them out a bit would help?
To be honest, at first I wasn't sure if I liked the contrast of the image or not... but after looking at it for so long, I think that the contrast you used makes the image absolutely outstanding! It gives the viewer a very thought-provoking and insightful perspective, and I LOVE the fact that you put your flowers all the way around your image, as opposed to only partial. Your image and angles look well thought out, and overall, looks very impressive!
