Susan portrait shot

A few weeks ago I was shoting my friend Susan, who is overwhelmingly beautiful and talanted person.
It's been the first time in a long awhile since I made a portrait shot and  if to be frank, I missed it terribly.
I'm feeling the most comfortable when I'm taking portrait pictures, like that's what I've been doing for years, even though I'm just a beginner. Several people asked me , if I get bored shoting shooting the same people over and over again. Maybe they do, but I'm definitely not. For me the better you know someone, his or her gestures,emotions, habits, reactions on pacticular things, the better you can show it in picture, even unconsciously.
