As an artist you need to be able to help the viewer visualize what a painting would look like on a wall, in home like surroundings.  There are numerous programs on the internet to facilitate this - I chose canvy because the rooms are very day to day.  I am a very visual person and can simply close my eyes or go in a daydream state and voila - I am able to form a mental image of what I want, but need to keep in mind that not everyone is so fortunate.  Surround yourself with beautiful art.
