Walking through the city '..

How about tilting the frame slightly to emphasize the free spirit of the bubble?

Well done regardless.

I like it very much...my only suggestion is to have added the "color" to the other bubble as well (though perhaps there was none visible at the distance). It just looks a bit odd that one (even though it is the focal point) has the colorings while the other remains black and white. Even still, an incredible picture!

very nice shot!  I really like the color and clarity of bubble with the soft focus black and white background!  Thanks for sharing! -chris

very clever however i prefer if the child was in focus as the bubble is a bit too intrusive.

Edmondo, I have often seen the use of one color object in a black and white image and usually find it inappropriate but this bubble is magnificent!  It is clearly the subject of your composition and I like the fact that it is the only element in sharp focus.
