First, infinite respect for your efforts and involvement.

I have been working in the luxury market for years. Selling Hermès products on the black market. Mainly in China.
I'm not willing to be harsh and hurtful. The two hostesses in the video looks like pornstars. I'm not smelling money but something hipsterish and burlesque. It is not that bad but it could be better. I doubt many people on this thread are understanding the wealth class, habits and way of life. Step in an Hermes boutique and impregnate yourself. Look at the customers, the staff, the quality and the refinement of the products. Soon you'll be able to smell it, even if you're not rich yourself.

Throw the flashy yellow. Use a nice hotel lobby or a rooftop bar.
Dress the girls with cocktail dresses.
Make people dream

Any form of vulgarity have to be avoided as much as possible. Blackcoin should aim arab oil muguls and Lafayette addicts. This is for the wealthy. The typical hipster buying his smoking at Zara should not be able to afford it. I think this is the spirit. The elite is the elite and do not like to use anything related to the lower class. I do not say this is good, this is how they are.
The luxury goods market is one of the best segment in the world. It is an healthy and growing market despite the global crisis. Analysts says it will weight more than a trillion dollars in the upcoming years, chinese and japanese running ahead.

May this be constructive and help a bit in your vision.
Sorry for grammar.
