Christian, I really enjoy the RX-100. I know there's a lot of hype around the camera but between 28mm and 50mm IT IS the best compact camera out there. And once you get used the somewhat limiting UI, it can be a great street photography tool.
I agree; the soft background really makes those rain drops shine!
Not really sure, but pulling the green back a little might prevent the eye being distracted by the grass in the lower-left foreground, but then again...
