Were the paint daubs used to add the dew? If so, may I suggest adding a couple of drops in the yellow area for a more believable effect?
If it isn't the dew then I can't see the effect which is great. Post production effects, just like makeup on a woman, should not be obvious.
As for centering the photo, I disagree. If, for example, OP wanted to use this photo for an article they could use the left side for the title. Usually I shoot flowers vertically but this shot may make me decide to change it up.
