Knowing nothing about corporate shots, I'd say the level of seriousness is about right - maybe a slight smile would be permitted but need to be careful there was no smirk visible. I don't think sharper is necessary, maybe some stronger skin colour.

I think the outtakes and the cats are great. Serious ones could perhaps have a little more space around the head and, as Richard says, a little more colour in the face - perhaps increase the saturation slightly. No sharpening necessary IMO. I'd definitely employ that man!
