A very beautiful drawing, and your tips are helpful for a avid drawer starting. My only quip is that the subject/face seems to be blank, dead pan, missing a spark of life.

Not that I am in any way a professional drawer myself, I am flat out getting two stick figures right, but I do like it when the picture/drawing tells a story, whether it is in the eyes or in the face, it just has to be a small story/spark.
