you don't even need contouring, i'd die for your cheekbones you're really pretty.
i have heard good things about the anastasia beverly hills contour kit (if you write that into google you can see people who've used it), but it's not available in the uk till jan 2015 (on cult beauty.. thinking about ordering it but not sure).
i've got the nars albatros highlighter it's supposed to be good but i didn't think much of it.. i preferred the bourjois highlighter it was in a book but they've discontinued it in place of a bronzer/highlighter book- i don't rate the bronzer though for contouring purposes
a lot of people rate the ben nye banana powder but when i put it into google generally the people using it have darker skin and it seems to work better
and this kit -
Studio 10 | Visible Lift Face Definer | Cult Beauty
which i don't recommend at all and regret buying
this is the kit that's supposedly really good
Pro Series Contour Kit | Anastasia Beverly Hills | Cult Beauty
i do find it easier to contour with powder over cream if you have a lot you want to cover with foundation/powder cause with creams it tends to ruin your work (i've found anyway in my exp)
good if you have no scars/blemishes/freckles though (i do though which is annoying)
i think a lot of it depends on the product you're using. i've never had the same results with the products i used when i look at people who've used that abh kit.
i find contouring one of the most difficult things to do in makeup.
