I think they could both use a little work. In the 'brick wall' shot, the focus appears to be on his ears; his eyes are soft. As well, fill light was needed camera left as his skin tone runs from a bright, ruddy red to almost alabaster white far camera right. Both have, IMO, unnecessarily distracting backgrounds that don't really coordinate with a 'suit & tie' look. As well, don't forget the small details: Dandruff on his lapels, skin blemishes, etc. No doubt that these are better than 90% of the work used for social media, but with just a little more effort, they could be a LOT better.
