Well, for starters, Joe appears to have only one ear. And no shoulders. And poor old Joe, he's floating in a sea of texture-less,inky blackness. Because the camera is mounted horizontally on the tripod, we can't see Joe's shoulders, nor do we even get to read what clever slogan is printed on his black T-shirt! Doggone it! On the overview shot you took with a second camera, or your cell phone camera, you had the camera oriented properly; since the subject was taller than it was wide, the vertical or 'portrait' orientation used in the overview shot showed us what we wanted to see: the tripod and camera in the foreground, the basement roof beams, the clamp-mounted work light mounted on top of the water heater (careful, Miley Cyrus might pop out of nowhere and dance on that pole!),and of course there in all his defocused glory, there stands your buddy Joe. Standing tall, standing proud.
As far as things to work on, I'd try getting a good white balance for incandescent lighting,and turn the camera to what's often referred to as portrait orientation, and maybe show Joe's shoulders a bit. Add a white sheet to the camera-right side of your set, to reflect some fill lighting back onto the Dark Side, so we can see that he has two ears. And, if he's up to the task, I'd ask Joe to wear a fancier grade of T-shirt for the next session--maybe one touting a favorite band, or even a favorite beer company shirt.
so.. there goes the ability to touch things up.
