I think this would have been much better image without the tag and string. Those to items really distract from the beauty of the rest of the image. Everything else looks nice. Just that tag screams Im ugly.
Nice idea and an interesting composition, but I think it would have worked better to illustrate the "greeness" of the Green Tea if you had chosen a different tea cup: one without all the "trim" and flowers inside. Also, traditionally, green tea is served in a very simple cup without a handle!
