Actually, if I'm really brutal, I would only keep the following, and get rid of the rest. (I'll explain why below)
Now let me explain...
As a model you have to present the best you can be. That is not always easy as the photographer can screw up what you are doing.
It is a dance you play together, and some just dance better.
The once I selected, portrait you, or your abilities best.
The other photo's do that less.
When revamping your port beware of the following:
* Don't show to much of the same (you'll get typecasted)
* Show as much diversity as you can... from soft romantic to gothic rock, from stylish fashion to fetisch nude and everything inbetween
* Make sure there are enough photo's any client (photographer, business... whoever) can lay his or her vision on top of. So make sure you have plenty of photo's showing the shape of your body, with not to outspoken clothing.
