Beatiful work here. A near perfect ad. The cup of tea with the box makes me sure of what the product is and everything is perfectly displayed. A little more space on top for possible text a cleaning up the small crumbs under the cookie are my only small picks. I'm still giving it a 10. Good luck!
The eye is immedeantly drawn to the cup as the colors contrast very nicely. The picture is very sharply in focus, which helps the eye chose where to look.
The lighting on this is very good, as is the focus. Having the tea pack and bag partly in the frame and partly out, though makes it feel off balance to me. Maybe if the cup and cracker/cookie/biscuit were also partly out of the frame in the lower left corner, it would feel more balanced (to me).
