Framing 

I followed the rule well as the subject is clearly framed buy windows in the background.

The subject is a blue milk carton, from the company TruMoo and is as stated on the carton, Chocolate flavored.

The subject is clear in view and is the only subject in sight. The viewer clearly knows the carton is the subject.

I believe this photograph was perfect as it is clearly obvious that the carton is being framed meaning I accomplished my goal.
