This was one of my favorites. I gave it a 10. I like the sky clouds and the trees. I like different objects in photos if they are in the background. I think the trees frame the drink!
This an not too bad picture. It is almost interesting. BUt don´t appeal so much to me. I had noticed many dsitractive reflections around the glass. The clouds add so much to the picture, but the trees seems to had much focus then distract a bit. The colour cast formed by all the elements are fine.
applying the rule of thirds would have made this a bit more interesting-to me anyway :-)
and maybe a different colored umbrella to make it stand out more.
but a nice idea none the less.
