Creating a car livery

[Martini]

Hi!

I'm buying a new single seater with a friend and we have to choose a livery. Since it's wintage (although it's new) and many colours are already taken, we thought we'd take inspiration from the JPS Lotus 72:





Our car looks like this :



Or this, this or  this.


So, the paint would be black.

On the nose cone, there are scoops extracting the air from the radiator, I'd like to have a gold trim around those three.
A golden nose.
A golden triangle/trapezium on the side (of the nose cone, still).
A golden circle around the maker's emblem (Crosslé).
The numbers will be the number Pi.

The "Classic Racing School" lettering will remain in gold.
The wheels will be completely black with a golden trim around. Or with the same amount of black and the whole polished aluminium in gold (better, just not sure it's doable).

The side will display this:




Bonus, it would be even better with the headrest (which can be seen here) in dark brown (like Havana)


Before asking for your help, I made a mock-up:




Please don't laugh too hard 
It gives a decent idea of what we want but looks terrible and I'm more or less ashamed to send it to the car company.


I don't know if it's out of the line to ask that here but I'd very much appreciate if someone could have a look and maybe propose something a little bit more refined 


Thanks guys
