Thanks for the comment everyone.
Whats your setup if you dont mind me asking?
These were shot in my 'basement studio'. If I get a chance, I'll post a wider pic of the whole setup.
The background is white seamless. It's actually a low reflectivity vinyl material, much more durable than paper but hard to travel with and the wrinkles can be a pain.
For lighting the background, I have two B400 strobes. Both mounted fairly close to the background (one is actually on a super clamp that is attached to the autopole which is holding the backdrop). These two lights are pointed up to the ceiling so, in essence, the background light is all coming down as bounced ceiling light. This set up isn't ideal because that light spills all over the subject but it keeps me from having to set up separate light stands for the background lights, which is important because I've got less than 12' in width.
The main light is a large softbox to camera left. It's on a 13' light stand, as low as it can go...a couple feet off the ground. I didn't want to go too high.
That's it for lighting. I didn't add anything extra for fill, but there was plenty of light bouncing around and the softbox was big enough to just about wrap the light around him anyway.
One thing I could have done, was to turn up the background light on camera right. The backgrounds lights were set evenly, but when the main light was added to the backdrop, the left side ended up a bit brighter than the right.
You got him looking at the camera most of the time
Well, I also took a lot of shots.

But overall, he was pretty cooperative for this shoot.
