It wouldn't be justified to pick any one of them because each one teaches you more for the next one but still if i have to choose one i would pick the 'passengers' one because managing the dark colours has never been easy for me.
Curious to know which is your favourite?
Completely agree with you on this one. Dark colors are challenging indeed.
hmm my favourite.. Very difficult to pick actually, because each one means something to me :)
But if I had to, it'd be Passengers :)
