@aliensalmon it's very odd that there is an elevator that leads straight up to their room.
But what do I know. it does that in iCarly so I guess it's a legit thing.
Autoshadows are most of the time a no-no, you should only use them in maps with light coming from a particular direction. You have no light coming from the left side of the screen and even then a wall wouldn't make a shadow that is only half a tile in size.
That leads me to my next point, to put some lights in there. Imagine what it would look like at night, completely dark. The character would definitely need some lights in their apartment/house thing.
I agree with cutting down the size a bit. The bathroom doesn't need to be that large, for sure. Although the kitchen would probably be a little bit bigger. The main room can definitely be cut down some more. I would put the bathroom on the right with a pathway going horizontal but that's just me and a design choice for this particular map.
