This advertising stuff is pretty specialized, so not sure any of my opinions would be worth much. Both images are rather eye-catching. In the first, I like the unconventional pose and the large areas of pure black and white defining the field and ground. [The model is certainly worth looking at also!]Something bothers me about the arch-thing in the back and the line of the model's hair. Not sure exactly how to explain it. The second captures a wide spectrum of emotions in the facial expressions, but not quite sure the emotions are "intimacy"? You say they hate each other? They seem to be sharing a moment, but not necessarily with each other... I do very much like the straightforward style. Again, this type of work is very specialized. I stick more with trees, snow, and gummy-bears.
