I realise the essence of this scheme is its pale, good looks however I would like to see a grey wall (slightly darker than the console table) to make a statement and help the beautiful mirror stand out. You could even introduce acid yellow and a little bit of black. That said, if you love rococo and pretty, this is probably your choice.
Simple hallway is looking neat and clean. White shoe rack is making area bigger. Mirror on the wall is giving open feeling. Flowers are giving fresh feeling. Lights are making area bright we can see Rectangle shape on the shoe rack.
If you keep in mind the decor of the rooms leading off your narrow hall, it's easy to trick the eye into believing that the hallway extends further than its boundaries. Choose harmonising colours and textures for a deceptively seamless link.
