Nice work! I agree with the above posters it was well done and I agree with their adivce(clean your lens, improve the soundmix and watch the jumpcuts).
Your lighting was good, but it could have been great. I know time is always an issue but I think you could have improved the lighting quality with a few extra steps. I can tell you are an exceptional lighting photog, so I would suggest buying a roll of opal, cut a big sheet or two that you can attach with clothespins(c47s) to the front of your soft box. It will soften the light that the soft box produces even more, it will feel a lot more natural and soften that nose shadow. Also throw a small sheet of opal, preferably two, on your back light it was a little hot but it was positioned well.
The b-roll lighting when he is on the couch was way too hard for my taste. I know the mood you were feeling and going for but it just was too harsh. It looked like it was just your open face light or frenel that was lighting him. I would have tried using your soft box in addition to the hard light to soften shadows and fill the shadows up a bit. Although contrary to the textbooks I would have put that fill light close to the key, it kinda gives ya a double key and adds texture levels to the face with out it going to complete black. Then if ya could have moved the key a little bit around to the left, it could have given it a little more polished look. If the diffusion or opal was at your disposal that day you could have had a couple large sheets on the softbox and the light would have fallen off quickly, still leaving your background dark and moody but softening your subject up a bit.
Im sure you were kicking yourself in the edit bay but watch the reflection in the picture you shot of the guy at his graduation. Just like your interview, take advantage of the fairly large space you had to shoot in. Put the pictures in a place where you can get some depth, kinda like the shot you have with the yearbook, get some kind of background in there even if its minimal. Even try lighting it like an interview, put them in the center of the room add a soft key and a backlight or two and gets some depth and visual interest in there.
If you do get some opal take care of it rips easy. Again nice work and you have a solid piece to consider for your demo.
