The concept and overall composition of this is very nice. But the too bright background jumbles everything together and overpowers the gumdrop trees. Distance (*even imaginary types) is often conveyed by a graying effect, as red and yellow tones are more short light waves. If you were to slightly desaturate that background with a gradient adjustment layer, and possibly increase the color saturation of the gumdrop trees just a bit to help them "pop" a bit more, your "candyscape" will have a much better visual presence. As is, if you squint your eyes slightly to blur the entire image, you will see that is a somewhat amorphous blob needing a more distinct focal point.
