Very good job using tiles for their intended purpose.
Don't listen to these guys saying that it was too big, it's not.
If you were to try and proportion inside levels to be realistic in size you would get something very funny looking.
The way you did it is superb and functional--exactly as it was done in A Link to the Past, which the tiles are obviously based on!
Whatever Nintendo did with the tiles is the right thing; Nintendo created the format to function a particular way.

No matter how much nicer than this a level could be made to look, none could be done more proper. You are a better level designer than the naysaying posters in this thread.
