Looks a little grainy on my screen, but it could be the look were going for. A bit more focus on the bubbles and grass blades and maybe bump up the saturation, this would really "pop" (sorry, couldn't resist) :-)
The bubble is in perfect focus and is gently nestled between three blades of grass that seem to hold it up. However, the composition on this photo could have been more interesting. Their is a dead leaf in the background and that could have been more effectivately integrated into the composition if you had taken the photo somewhere where there existed a single reflection of a tree within the bubble. The view would then have instantly connected the leaf with the tree in the bubble but as it stands here there are several trees reflected such that the connection is not strong enough to support that relation.
