If you're interested, some pointers that may be of help lighting wise (maybe not). First off, that picture looks great. I wouldn't say there's anything at all wrong with it.
It looks like you used one light, slightly behind and to the right of camera. That would be your key light. You look like you softened it pretty good. If you are at 6 o'clock, and your subject center of clock, a fill light could go on the opposite side, anywhere from 7 to 9. Usually, your key could be slightly harder, and the fill light soft and wide, but they would balance each other so that neither was too apparent. A backlight, should you choose to use one, would be opposite camera to either side (10-1 o clock), and above, in this case about six foot off the ground, or above your backdrop, making sure to flag it out of the lens.
With a single subject you generally get much better results being further back, zoomed in on a longer lens. This will fuzz your background and pop your subject.
Keep in mind that while those are general rules for lighting, there are no rules. I've seen the rules followed slavishly and I've seen setups that break all the rules. That's why guys get paid obscene amounts of money for an amorphous skill!
