What I like most about this image is the contrast of the deep, tea-infused water with the dominant white background. The effect is unique, and it works well. Also, the 'overflow' is well captured. I would have excluded the lemon slice because it's distracting, and then you could have all of the viewers attention focused on the tea. Either that, or put the slice in the glass, on the rim--that way, it has utility and enhances the image
