To roof or not to roof

Having looked at my hanbok painting on the wall for a while now and I still like the way it is.
However my curiosity is killing me.  Am I never to find out what it will look like had I painted in the roof.

I figured out a way to make it work.  I could do this digitally.  Photoshop comes to the rescue.

This is the painting as it is, without the roof,

and here the roof is digitally added with the help of Photoshop

I didn't bother to select the correct color for the roof; and sepia happened to be the default color I had.

I thought I was being clever when I devised this scheme but it seemed to backfire on me.  I like both versions, each with its own ambience.

Now what do I do.
