How to Know if a Room is "Done"?

I don't know if anyone else struggles with this, but I feel like I am never done decorating a room.  I feel like it gets "close enough" and I stop and focus my attention else where on rooms that need it more.  Case in point, my foyer:

Having taken photographs of this room, I can now pinpoint exactly what I want to change about it.  Those baskets are irritating me and so is the lamp shade .  Also, perhaps another rug to cover up the tan tile? (Definitely not my choice of flooring). 

The things I do love about the room are the lantern chandelier and my owl-umbrella holder.  I'm not sure if it's actually supposed to be an umbrella holder since it's a little on the small side but I love it so much, I don't care.

Any thoughts/suggestions? Does anyone else ever feel like they always want to change something about each room?
