These balloons are lovely. I'm not sure what's bothering me about the photo, though - maybe no sense of context or not enough negative space? Still, nicely done with vibrant colors.
One of my favorite ballooning photos in the challenge I've seen. Nicely shot. Only nitpick , the reds are a tad oversaturated and the shadows a little too dark. I can understand how just boosting the contrasting can cause those side effects, just needs a little tweaking in PP.
