for correct tiling purposes it can be very difficult to get everything lined up in the same perspective, especially for floor tiles. but it's also important for the other items to have as much depth as can be managed and so some compromises are made. i'm sure there might be a better way to approach but i'm not sure what that would be without the tiling not working correctly. also i make a judgment call on lighting as most eyes wouldn't expect underlighting for floor tiles and it might feel like it's communicating a different atmosphere.
This is nice but there are problems with the floor tiles. They are seen strictly top-down while the furniture has a slight perspective, and this is made worse by the highlight which should be on the near side of the tiles instead of the far side. Also shouldn't they be visible through the foreground windows?
All the tiny objects are very readable, good work on that!
I agree about the necessity of a perspective compromise, but I strongly disagree about the highlight!
There wouldn't be any underlighting at all, as the floor is horizontal. It might help to imagine or draw a side view, with bevelled floor tiles, and draw light rays towards the viewer's eye. The shadows indicate the light source is a little in front of top-down: the front bevel of the tiles will reflect more light towards the viewer, the back bevel less. Conversely, with the present highlight it's not hard to see the tiles as vertical ranks. I think you should try it just to see for yourself ;)
