Hydrangea and Light Bubble

Canon EOS 60D, Canon EF50mm F1.4 USM (50mm, f/1.4, 1/320 sec, ISO-100)

I tried to use light bubbles intentionally to decorate the images of Hydrangea at Shinjuku Central Park.

But I find it quite difficult because the direction of sunlight is fixed. I must find an appropriate place to stand on, where the sunlight must be partially interrupted by leaves or something similar. Hmm... I need more practice...
