I have never come across you before and just had a look at your port and with all due respect to you, think you do need an update.
From what I can see, on the plus side, you are a very pretty girl and I would imagine if you got in contact with some decent photographers it would not be hard for you to update your images over a half a dozen shoots or so.
It looks like you are a promotional model more than anything else, so if want to broaden your port, why not add some other styles in there as well.
Have a look on here for some photographers that you like in your area and approach them for a shoot.
I'm sure you could be very popular if you put in the work.
