Again i am going to disagree. A portrait does not mean the shot has to be straight on with eye contact. The disconnected feel of this images could have been the OPs aim. MAybe the personality of the model is distent maybe she is locked in her own thoughts. Eye contact or no eye contact can really shift the feel of a portrait but that does not mean its not a portrait. A portrait is simply a likeness of a person this can be shown in many different aspects.
Are you going to tell Brian Duffy his portrait is wrong because Bowies eyes are closed
No, of course. But he is an experienced photographer who is conveying something with his photos.
The OP is a self confessed beginner and needs to learn some basic issues first.
In 999/1000 a portrait will show the eyes and the face because the photographer is trying to make some contact and tell the viewer something about the subject.
There's no contact here and no idea what is going on.
This is a miss as a portrait because nothing from it and all your fabulating about 'cold expression warm color 'doesn't mean crap.
