Heritage building environment- unreal engine

hi guys,this is my first complete project in unreal engine and after 2 months of efforts i can say that is partially finished,i still got many things to learn about lightings and shaders for example, also the garden /outdoor area requires more hours.
My intention was to create a "mini-world", so is composed by a little garden, a pool and the main building, in it you can find:
a patio or balcony with sun umbrellas, relaxing chairs and a little jacuzzi.
a meeting room with screens,chair and a whiteboard
hall 1 floor with plants, draws, bins , door rooms and elevator's door (for future implementation)
hall 2 floor with elegant draws, red carpet and wallpaper
elegant bar lounge area with black and white marble on the floor and black leather couch.
As said required almost 2 months, all the basic structures are mode in maya and textured in substance painter, unreal for the rest.I'm planning to extend the project with maybe another level or 2 and interactive elements.
thanks in advance :)
