Basic skills should be solid, the depth of lines should be accurate, and the position you write should be chosen. In addition, exercise your eyesight and observe why the material of this pattern is painted so well and where it is painted so vividly. Look at the thickness of the lines, and the works you make will be very vivid after learning these. What is obvious and what is not obvious will directly show the ornamental effect. You must learn these basic things well, and everyone who paints will have their own style to reflect your style. Don't paint so dead, and don't copy the original picture to add your aesthetic views and opinions to the painting.
