Well, for me you convert to the King of natural portraits as the time passes by, Marcio! They have both a very natural look and feel and also a great care for details and exposure. This time the emphasis of light on the man on the foreground made him stand out very prominently, and this is accompagnied also by keeping the DoF on him. Most details of his cloths are not there but the face is more a sculpture than a flat depiction on an image. The timing was also great for that!
It could also have worked as a square image without the other guy, but I find it very absorbing the way you presented it! Very prefessional, very mature work indeed!
