|The new PTV-branded VLocity livery (via VicSig)|
This gem-facet pattern is being slowly phased in, but is ultimately intended to be common to V/Line, Metro trains, Yarra Trams, and the various metropolitan buses - everything that comes under Public Transport Victoria (PTV). A unified approach to this sort of stuff does make them stand out as part of a wider network, and not just a bunch of transport options competing amongst each other, so I am in favour of the initiative as a whole.

Like I said, I'm a fan of the gem-facet pattern, so I think if you made it less messy with those few changes, they would look better than ever before.
