#51, if I was there, I would have focused on the front person, then had the person at rear blurred out. this way I would have led my viewers focus to the front person whom I have intended as the focus point, through the sight line of the person at rear. (he was peaking at the front person) Using the sight line of the rear person to imply my viewer where is the focus point is more natural and smooth. don't you think? #54 is another one I liked. It matches the one-third layout rule. good on eyes. there is a little flaw - the coffe cup is over exposured. I also found that some details missed on his face due to the over exposure. All others, limited by my knoweldge, I don't quite get them. These are my opinions, only. hope you don't take as offence.
every time I saw your photos, I always get a step forward, big or small. Thanks for sharing!
