The charm of oriental painting is to express everything by line and rough stroke only.
Using various colors can distort to the original intention of artist, but using only one color of black can more express both objection and intention of artist.
If color & water are restrained as much as possible, deep inside of objection can be more expressed detaily,
I can more concentrate on my art work because I don’t need to worry about suitable color selection.
This art express another self-portait. One side express to self depression, other side express to self realization, in other words this art also means that most of us have both a static ego and a dynamic ego together.
