We will depict the tree in parts to get everything correct and beautiful. We’ll start with a trunk.
Draw two lines up from the trunk to show the shape of the crown.
Draw the ramified branches in stages.
Their location makes the tree look big and powerful.
Just mark the contour of the deciduous part of the tree with the help of a wavy line not to complicate the drawing.
Add the similar “wave” at bottom.
The root system of big trees is usually heavily ramified. Draw the oak with roots.
Show the crown’s volume with the help of extra wavy lines.
Draw the relief bark.
We show how to draw an oak leaf in another instruction. But if you are drawing together with children, you can draw an oak without leaves.
