Very well done to the winners, both excellent shots & good and Shiny™
Above: Cutter - This must have taken some time & patience. The end result is really good and the bubble/reflection is top notch. I know you were putting the bubble in a place but I think the background is a little distracting and would have benefited from a shallower dof (or blurring pp). Also, perhaps the image could use a little punch (I would say 'contrast boost' but I understand that term is ©Kristin Moat
) to really bring out the roundness of the bubble and colours.
Below: Wattsy - I think this is a superb shot in its own right and is clearly technically excellent. Just didn't shout ROUND to me for some reason. Top work though.
So, collections now is it. For my sins, I'll be sucking in great lungfulls of water-laden Welsh air this weekend so I may be a little short of subject matter.
