Photos 2 and 3
First off, they are very well executed and there is no technical quibble I would care to speak of. The reason I thought they were less interesting to me is that they aren't interesting portraits per se, because there is no human face. They are photographs of costumes, much like a photograph of a mannequin. What makes human portraits fascinating is our relationship and understanding of humans. When a full mask, or costume is employed, what of the human can we see? They are nice clear photographs of costumes, but I don't develop any relationship with them. If the costume was placed in a larger context, more interest might develop for me.
