Fairly decent portraits.
It looks a lot like you grabbed a point & shoot and took these photos yourself with one hand.
I would expect people photography to be more candid shot of people in public.
What kind of camera were you using?
What is the composition you were going for?
There is a lot of thought when it comes to portrait photography.
Lighting, distance, etc..
I would definitely recommend taking a look at some beginning portraiture tutorials and such.
