Certain parts of the painting have been damaged as it's old, but even then it looks like colourful and spectacular. There was no artist's name on the painting which confirms that this painting must be at least a hundred years old.
While toying with photoshop I altered the original painting a little to give it a dark look.
This is a sketch or drawing of Ravan or Ravana, based on the painting above.
