#1: This does express the theme of apathy but I think it might benefit from a lower or higher perspective. The subject should be apathetic, not the photographer. A normal tripod height camera doesn't give a new perspective. Also it is a bit oversharpened. Notice the bright and harsh edges of your t-shirt, the curtains, and door frame etc. The black frame around the picture merges with some in-scene items and becomes kind of distracting. Maybe lose the black frame too. At least it doesn't look like a typical overdone HDR but maybe a touch more light on yourself would make it more about you and less about the room.
#2. This is a good portrait. I like looking at it. Sorry, I don't have anything condescending to say about it yet. OK just one thing: maybe clean up the white thing by his right foot as it causes the eye to look there too much.
#3. It's a cool shirt with a good message but it is being worn by Mr. Apathy who doesn't look ready to F*CK anything. Was it intended as irony or a kind of satire?
