Draw the outline of branches, the bifurcation of branches, the outline of leaves, the front and back coverage, paint the branches brown, the leaves green, the lawn turquoise and the trees dark brown.

The first thing is to draw the trunk of a big tree. When drawing a trunk, you should pay attention to the fluency of the lines used and the subtle differences on the trunk. Draw a sketch below. Draw curved grass with curves to make it look more alive, and the lower part of the tree is finished. Then draw a crown on the trunk, draw a pattern with ripples like clouds, and make a smaller crown near the trunk. Then, the outline of the tree was drawn.

Finally, the outline of the leaves is dyed green with pigment, the middle is light green, the tree body is brown, and the lawn is painted green, and a tree is completed.
