I like this shot, because in every detail that i can see there eminates Grace. I love how similar and diferent each model is dressed and looks. There is harmony in there expresion. They don't seem like two seperate people, i can tell only by this picture (it may not be a fact) that they work very well together.

The milk in the champagne glass is very unusual yet understandable, same goes with the pearls.

The concept of white, is complemented by their sking tone, and every other detail.

Over all I think you did a magnific job!!

Ps: Keep it up!
