This camera would be perfect for what you want it for reason being its small and near for a dslr and remember this model has the wifi capabilities for portrait now you can put your self in the picture :)
Peach, for portraits you want to use a 70mm lens, or greater. I guess that it's just an odd thing about portraits and how the lens works and the shape of the face. Otherwise, the D3200 is a very nice light weight camera. I purchased two of them, for my daughters and they work well.
