This is such a nice scene. This image could be improved a lot in several basic ways. First, it probably should be made level. It may have been your intention, but the amount of angle just makes it look unintentionally crooked. The daisys and the background on the upper left are badly overexposed. It appears the image is oversharpened. What might work better for this shot would be to take the picture from near ground level looking up with one or two of the daisys prominent in the frame and the statuary big in the background. Using shallow depth of field where the daisys were in sharp focus but the statuary in much softer focus in the background would make a good effect.
You might try this a different time of day. The sky is too bright and the flowers seem too bright too... not enough detail in them. Also, if you follow the rule of thirds it helps the dynamics of the photo... it seems a bit stagnant as it is. I like the bent flower that seems to be joining the angel in prayer.
