Substantially better, I would move the negative space to the other side of the frame as the image would flow better.
That's the expected composition and precisely why I sometimes do it exactly as OP did...and like it that way. It obviously requires the right posing and lighting but putting all subjects to the left looking right and right looking left gets kind of boring after awhile, IMHO. Depends on intent really. Most executive headshots are cropped center anyway though so left or right and negative space is moot.
