I've only recently updated my portfolio after the new year, please do let me know what you think

Beautiful look Charlotte. You got a deep and artistic array of samples in your port which are eloquently designed and showcase that side of you very well. You may also want to consider a better full length body shot in bikini or lingerie as there still seems to be some mystery as toward your overall physique, which could hinder you in landing more jobs. Also you might want to try a really good headshot of laughing or smiling. Being diverse opens up more avenues and increases your marketability. Continue with the sensational work. Best of luck in 2015.

I like what you have done!!!

One suggestion: This is probably your worst image



You might want to replace it with something else when you get a chance (but don't until you get other input).

But just one worthless opinion.   

An excellent portfolio but it needs a couple of additions: 1) a full length shot - the one you have is too far away and more expressions from you. The ones that are up are very much the same.

This is my favorite:

My least favorite


Nice variety except for expression.  And thinking of expression, the last two are too much alike in expression.  I'd suggest dropping the more manipulated one of you in yellow.
