Wacom Sketch of Geisha

Been getting more use out my wacom tablet recently, had it over a year and still not gotten to grips with it.
This is a sketch taken from the wonderful "Paint" magazine

This is what my pics would look like  if I had the bottle to apply more depth and darkness or something.
What I have done here is open the above sketch with the windows "Paint" program and pressed the "fix" button which has made such a difference don't you think. Comments welcome
