It seems you gave some thought to this shot, which is nice. I like the angle and the dof. For the composition, I think it might be improved without the dark area in the bottom right corner.
I think technically, its done pretty well - with clear focus where you want it, good colors and exposures. The subject itself, I don't find interesting. Whether I like yogurt or not, I don't think I'd be inclined to put a photo of yogurt cartons on my wall.
It does meet the challenge and is an okay photo, but just lacks appeal for me.
