My only hint about this work would be to never try and be someone else, don't ever think "I would love a style like that" because at the end of the day everyone has their own unique style!
I approach my work in several different ways, for commercial and fashion shoots I do alot of planning and there is a lot of prep work! There is obviously a massive team behind me for shoots of this nature, for example the Make-up artists, Models, Stylists and Hair Stylists have a lot of planning of there own to do, but my photographs would be no where near as refined without them.
But when it comes to personal work, it just happens! I have a few friends that have really helped me along the way (Tommy, Jono, Graham, Allyce, Eve and many many more) I can not fault one of them! Sometimes a few of us are together and the images just happen! For instance the whole dreamer series was done with no planning of any kind.
