Icon Design for A Friend

I helped my friend's friend to design an icon for his business. 
He would like to update his business icon, and asked me to design a lock or a man as the icon, in similar style as the previous one (first picture).
The two black and white were my finalized idea as the icon (after brain storming and had not showed it to him yet). 
And the color one was the real finalized design after got all the feed back and approval from him.

* logo on each character has been hidden purposely (including in the previous icon)
