Logo Development - What do you prefer?

I'm looking for your opinion. What option do you prefer? 1-5?

The logo is being developed for a consultancy service that aims to focus on people as a priority. My idea is to subtly show the importance of people by using the two "o"'s to create a simple icon of a person.

I can't decide how subtle to make it, so I'd love some feedback.
