It has to do with content density. Games that are dense with content (i.e. things for the player to do which will give the player enjoyment) are funner to play. SO theoretically, there is nothing wrong with having huge maps and huge buildings if you can find a way to fill that large space with engaging content.

I will say that I really liked the building's style. When I think of 'modern' style in Graal, it always occurs to me that Fourside (Earthbound) does a similar style, but much better. The rest of the game is in a similar perspective to Graal, but when you travel to the big city Fourside you find that the perspective is isometric for the buildings and city block design. It's really well done, but your building reminded me of that style.
