Toverland
confirmed Fenix is not finished yet. They're still working on an
extra scene, in the bare dark space when you leave the station.
That will change and even faster as expected. Probably the extra scene will be ready
later this year.
The left wall of the station building (where the train enters the station again) will probably receive theming too, but when is not yet known.
EDIT
Djengu River finally received the fully rock themed station it deserves.
EDIT 2
The queueline of Fenix was pretty dark. People complained about it and Toverland immediately worked on it. More light.
