What's wrong with the picture?
1 Side rear-view mirror missing (disneydreamer98)
2 Missing door handle on pilot's cabin (TrendyMagic)
3 "D" logo changed to purple (TrendyMagic/Tampa)
4 The trapezoid is purple, not white (TrendyMagic/Tampa)
What's not wrong?
WDW wording missing.
Missing sensor thing at track level on monorail.
Doors missing track, windows, people standing clear of them
Still one thing remains wrong with Monorail Lime

Hint: Please stand clear of the doors.
Hint 2: Nothing with the doors themselves... (aside from the pilot's door handle missing which was already covered...)
