All in all good.
Camera axis is a tad high on 1 2 and 4, try to have camera at same height as his nose ( no down tilt or up tilt of lens when doing actor headshots)
The agent wants to see his look not your artistic touch. The lighting needs to be 1:1 , very flat. You did this well.
The agent likes black cloths ( your model/actor knows this ) . Remember that its not a portrait shoot its for an agent to evaluate a look and that is important stuff to generate work for the client.
A few rules are No hair in the eyes. No jewelery, No logo on the cloths, Very flat lighting .
Break the rules of portraiture, we tend to find the angle that they look best and work from there, but for there headshots and comp/zed cards its about showing the look they have.
Those who are very good at this (giving the agent what they need) , get a lot a referal work from the agent. Most agents will tell there client ~ Go to so n so to get your stuff updated. It can be bread and butter work.
Nice Job!
