Lighting is too strong for my tastes and you can see fingerprints and water droplets (?) on the the metallic decorations. But I guess that's the point?
These are too pretty to be tacky. I'm not sure what the significance of the jugs in the foreground is, but to me it doesn't really explain the sense of tacky and it does take away from the colors and metallic textures of the decorations. IMHO if the point is that metal trees are inherently tacky, the tree limbs should have been more prominent.
Leave it to starbucks. Tacky tacky tacky. Tho those thermoses are pretty elegant... Nice composition, I'd like to see a color difference between the background and the thermos wrap and - if possible - wiping down the reflective surfaces so that the fingerprints aren't so distracting. Seems like a slightly noisy photo, too (high ISO setting?). Good eye.
