The background does not add to the photo. The tea bag's tone looks a little dull. I would rather have seen a brightly colored cup or some other accent. I like the concept though. 6
Lighting is rather dull and flat - on camera flash? The light fades quickly leaving the cup in partial darkness. the right edge of the image has a distracting background.
The composition for me works terribly well in this. The major downfall for me is the lighting. I'm not sure if it's the one from your camera or not, but it turns the picture off for me and upsets the whole atmosphere. I'm not sure if the entire setup puts of the picture as well, but I would have loved to see more contrasting colours to make it more appealing. It could be because I associate tea with happy, soothing times and this gives me more of a depressive/dull atmosphere. So a 5 it is.
