Was this done using a DJI Avata? Good Videos. They are well shot and smooth. That second video looks a bit smoother but is partially due to the larger size building I would think. In terms of constructive criticism, I would recommend getting as close to the walls when panning a room. It gives that grandiose feel and, if done right, gives more room for fluid movement. I personally really like starting from a lower altitude when entering a room(when applicable). That perspective change as you enter a room slightly rising before panning across always looks really nice to me. That being said, these are merely what I like to do in my style and just some Ideas to try as you progress✌️
