When talking about drawing gusts of wind and the tree, it was hopefully easy to repeat and follow the stages. If you have drawn the boundary line of the sky, this will help you identify where to start drawing the wind flow. Drawing leaves and petals gives the impression that the wind is blowing, so I recommend this effect. In this step, the power of the wind is drawn, which is noticeable when flying things like leaves and other small plants in the air.
As a result, you achieved another goal – you drew the wind, and not just a boring sketch of it, but a comprehensive wind that can always be seen in nature.
