Josie - there are some nice pics, but there's one thing that concerns me. Most of the pics are about a year old, so if I wanted to book you I'd have to ask you for some up-to-date photos. With all due respect, up-to-date pics should already be in your portfolio. It shouldn't be necessary to ask.
(Hope that doesn't sound rude. It's not meant to be.)
The pictures are great but they are quite old so for a start, people will have a doubt as to whether you still look like that, so getting some up to date ones may help.
They are also really only showcasing one style - lingerie / soft glamour, and two of the pictures are virtually identical.
Your port notes could be trimmed and still say the same, you have to get and keep peoples attention - anything too complicated and they may move on to someone else.
Mentioning the chaperone is the right thing to do, I wont say anything more than that
