What makes a good portrait is good lighting through the whole photo. Also there is no spots with over exposure, and your main subject is in perfect focus. This is a good portrait because my subject is in perfect lighting and her color looks amazing. She is so clear that you can see all her fly away hairs.
This is a good portrait because its not the standard sitting up straight portrait and her smile is a genuine one. Also the coloring is really nice and it has a cool tone all through out the photo. I also like how her body is in a slight slant and it makes the picture more interesting to look at.
This is a good portrait because she is the main focus with the background all one color and her being crystal clear. Her face is also refreshing because its not a normal smile its something different. her posture is really nice in this picture and her outfit is pretty being a nice color pink with the gray background.
