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!
I like the idea and perspective. I do wish this was a real photo. That would be so rad. The shading on the leaves of the flowers do not match the fact that there are clouds in the sky. Also, the flowers on top of the frame seem out of place and not needed.
i wouldnt have initially thought they were seperate images, like at a glance its not something that is going to be revered but i could see it working as an ad or something i like the contrast and the colours. blue and orange/yellow is always good, very popular right now too
you can tell that the dewy grass on the bottom corner and the one higher up are the same though, which sort of breaks the illussion, same for the flowers you might benefit from finding another image of the flower to add in, or at least manipulating some of the flowers by taking out or adding petals where they werent on the original, just to change them up a bit. thats just something that people will pick out also, you might want to change the tinting on the flower on the left, get a bit of that sky blue in there, and darken that top right daisy maybe, it looks very cut out.
this does make a good illusion upon first glance though (again why it would work for ads)
Looove the colors, even though I feel a bit like the angle is weird, somehow. Almost like the sky should be shifted a bit so the rays are farther down, or closer to the center. It looks a little off there, but I can't get over how well you edited the colors. The green is so bright in contrast to the soft flowers. Pretty wicked, that's for sure. I love the perspective, but, like I said, the angle seems the slightest bit off, if that makes any sense.
