It's been a long time since I last saw a Vance & Hines paintscheme,of those bikes I like the Lucky Strike homage paintscheme best.
I think a twin round headlight fairing would look really good & suit the retro vibe,especially in the two tone blue Gauloise colours.
They all look rather high at the front. And I'm not keen on that stubby exhaust - looks a bit cheap and chavvy to me. And lastly - the Sonauto 'Gauloises' colour scheme isn't how I remember it - there was a fair bit more yellow in the mix as I recall.
There were a few Sonauto-Gauloise colours,that one up there reminds me of the Patrick Pons colour scheme.
My favourite was the later two tone blue colours with the neon pink & grey piping
