Abstract Landscape 15 x 22 inches watercolor painting with ink outline

This is the finished abstract landscape watercolor painting.  It is painted on 15 x 22 inches Arches cold press watercolor paper.  More ink outline is drawn into the distance hills as I feel more texture is necessary to complete the overall feel of the painting.  The ink outline was done using a permanent marker and I have been using the Ultra Fine Point Sharpie.   I wonder if this is a good technique for stil life.  When I do the outline after the water color wash has been lay down, I have to be careful not to over do it and also the flow and shape of the overall design.  It is a good idea to do an area with the ink outline and place it on an art easel to view it for a period of time before you decide to do more.  Once it is applied, there is no way to erase the permanent black lines.
