Alrighty, now we are on to My Private Jet!
Start up by your cuticle, following the shape of the 'rays' and then make it a straight line down. I have made it so just under half of the nail is covered by My Private Jet.
Other holographics you could use:
OPI DS Shimmer
China Glaze OMG*
China Glaze Sexagon**
Color Club Worth The Risque*
Color Club Revvvolution*
*These shades are very opaque, so they would be silver rather than having the black come through.
**This shade is very dense but not 100% opaque. It could be interesting to use this one.
Feel free to ask me questions :)
