I have a big baby face and would like to give this whole contouring thing a bash. I was never very good at art in school and thought I'd seek some advice before I cake my face in lines and light powder. 
Does/can anybody contour & highlight? Is it as easy as the youtube tutorials suggest, what is the likelihood of me looking like an absolute clown and what makeup (plus makeup brushes) would you recommend? 
I am very pale with blue undertones if that helps. TIA!
