It looks easy drawing leaves and flowers like these. These are practice pieces done during my Chinese brush painting classes. The teacher does not teach. We have to copy the paintings in the textbook. The teacher looks over our shoulder and tells us if we have done it right and if not, we should try till we get it right. We produce drawing after drawing and when he says "okay" that's what we labour for.
This painting below is an original. A friend liked this very much and I gave it to her.
