I like this, the composition is good and the border adds some pop, but the purple in the upper right hand corner really crowds the shot. A simple solid colored background would really make it stand out
Another version of this concept is also in the challenge. This is a nicely composed take on the cliche. I like the lemons in the background at the bottom left, but what's that purplish thing in the top right?
make lemonade! nice shot great composition -- the focus seems a bit soft (although all this yellow so far in the challenge is hurting my eyes) and I'm not 100% sure I'm digging the border. Great composition though, and good use of the shallow DOF to bring out the lemon on the glass.
