Both of these photos are crisp and expressive. However, what they are expressing is much different. the first photo expresses the person while the second expresses a brand.
Commercial portraits often shows a subject that is using a product or doing the thing being sold. The color and style often matches that of the magazines style and makes room for tittles and other text.
The thing I like about commercial portraits is that they are expressive. However they all seem the same.
