I would make separate sections for the special effects make up and the commercial/beauty makeup.
If the website is to attract clients for the beauty side of makeup, I would change the main image on the first page to reflect this.
Maybe rather than having portfolio you could have three separate pages for your work (special fx, make up, nails), and then just one separate page with all your prices on. I think it would make it a bit more clear and easy to navigate.
I like the logo but I would remove the lines 'make up artist & nail technician' or move them so the the logo text is in line with the menu.
I also personally think that the menu would look better just as clean black text, without the grey boxes.
On the Nails page there are images overlayed on top of the last few lines of text. Apart from that I would suggest making sure that the images throughout the site are all lined up and that the organisation is consistent throughout.
Not so much to do with the site but maybe you would want to change the line: Falsh Lash Application £8 (provide own lashes and get £3 off!)
I was going to say it sounds like down-selling, I also just noticed copying that line here that False is spelt wrong. (My spelling is terrible so I can't talk, but maybe run it all through a spell checker to be sure)
I'm not trying to be critical, just trying to give as much feedback as possible
