Superb photo. I love everything about it except for the border (and what's with the extra white band at the bottom of the border?) The hint of green in the shadow of the glass is great. The lighting is superb - especially the gradation from orange to white in the background - top left. Keep up the nice work.
I came back and looked at this photgraph again and I must have been tired when I looked the first time. So I updated my comment to say that I really like the orange and blue together. I also find the composition appealing.
Fabulous composition. The blue drink is great. The background is really nice, though I don't think I like how the shadow seems to curve up, showing how the seamless background was made. It's also a bit grainy and has JPEG artifacts. But the blue drink is so deep and rich in color, it's great. Your image is less than 50KB... you have 150KB to use, please use as much as you need to get clean JPEGs for the chalenge.
