LinkedIn / Social Media Headshots

A lot of photographers get the shakes when they have to get in front of the camera themselves, but you can't really take a great picture of someone else if you can't do it to yourself. So here's mine. 
Actor style head shot that's not too corporate but neither laid back. I normally tend to switch lighting style depending on who I am shooting and what's it gonna used for. 
I don't particularly love a full ear to ear smile, but I do love a cheeky smirk, suppose it's a neutral face which is neither too happy nor too grumpy looking and let's you use it in a variety of situations. 
What do you think ?
Smile, smirk or no smile ?
