The main focal point for the level and in fact the game has to be the huge steam tower inspired by Beetham tower. It wont be a playable part of this level or many other parts of the game but will always be there looming above. Along with the tower there is the large hanger and airship that rises above it.
At the beginning of the level when the player has to get into the compound the overhead wire that they will use will act as another focal point of sorts.
The steam tower will appear between the buildings at various intervals where the line of sight is correct.
The scale of the hanger building will make it another focal point, the front entrance especially due to the activity there.
