Pin-leaf trees generally look like: sycamore trees, maple trees, round-leaf trees, broad-leaf trees, etc...
Pin-leaf trees use the double outline method to draw leaves. The lines should be flexible and layered to avoid dullness. The lines may be thick or thin, clever or clumsy, but we must pay attention to the coordination of the whole picture.
Different hooks and density of leaves are the main means to distinguish the relationship between the front, back, left and right. When clipping leaves at the back of the painting, you need to be aware of its ins and outs. Even though some branches are not visible (hidden behind the leaves), you still need to feel where the branches come from. If there are branches behind the clipped leaves, pay attention to the spatial connection relationship. Do not clip the leaves with two lines at the same time. The two dry ink lines must be connected one after another.
