I'm not sure if adjusting the levels and/or the curves could have changed the color cast on this one. It seems it was shot under an incandescent bulb. Also, it needs a little straightening of the horizon, maybe a crop, rule of thirds, increase saturation, increased brightness and contrast and finally sharpening.

This looks to me like the white balance is a bit off, too much yellow. It's just a tiny bit out of focus too. But that's a fantastic drink, love the parasol :)
