well....i think the whole image is just a tad too dark, i don't see any evidence of rain, and it is quite distracting that the fly, a very important element in your photo, is very out of focus. sorry :-/ but keep at it, practice makes perfect :-)
It took me a while to figure out why you had focused where you did (I presume ot see the water). Taht said, the fly being out of focus is really distracting, and because of its location in the frame and coloring, tends to become the main focal point, and its lack of focus is distracting.
If you could have had deeper depth of field (not always possible with macro, I understand), it would have been more effective.
Could have been less shallow depth of field. For this image, I think having it all sharply focused would have improved it. But that is only my opinion so don't take it to heart. Can't please everybody, as I have more than discovered in these challenges.
If the fly and tips of the inner flower parts were in focus this would be more impactful, also the colors seem a little dull but might just be my monitor. Like the idea though, keep trying.
