Wow, first of all are you sure you're new to modelling? Your images are beautiful and you have a very pretty face! Shame you live so far away, I'd love to do your make up and work with you on a shoot! I've seen way more experienced girls portfolios and they don't look half as good as yours does.
I'd suggest trying out different styles of fashion, maybe do some vintage style shots, something that has a lot of colour and maybe something that shows your softer side. Other than that I can't say anything - you've got some great images. Keep up the good work!
