Abstract outline on watercolor paper

The above is an abstract outline on 15 x 22 inches cold press watercolor paper.  It is going to be done in transparent watercolor and the lines are first drawn in with pencil and then with a perament black felt tip pen.  I will give a hint of what the abstract is after I finished the painting in a few days.  Watercolor and gouache might be used for this abstract watercolor painting.  I like to experiment this line drawing with felt tip pen comparing with the ink resist techique I shown earlier because it gives a more define line which is more appropiate to this abstract subject.
