Petros, thank you for your kind words. Yes, the kids are blowing bubbles and I did shoot them from the front as well. However, like yourself, the shot just brought back fond memories of childhood for me too!
You've done a wonderful job here. This photo brings back some wonderful childhood memories! Generally speaking, I'm not a big fan of the coloring effect you have opted to use, but I don't mind it here, as it makes it a more "fun" image. Are the kids blowing bubbles? Do you have a shot of them from the front?
