Switchback Railway Carriage Car Colour Experiments

Colour experiments for my ride carriage. In the book it is a carriage brought from Australia so I looked at existing Australian horse carriages. It is also supposed to be very luxurious like a royal carriage so some of the colours and shapes are from them. The carriage is going to be wooden but I didn't know whether I wanted the wood colour as well so I gave that a go too. I'm not sure which I prefer though so some feedback would be great!!
