Vary the leaf shapes and sizes for a natural look
Darken the trunk and major branches
Add bark texture with short, uneven lines
Shade one side of the trunk and branches
Add shadows within the foliage for depth
Erase unnecessary guide lines
Refine the silhouette and details
Add ground lines or grass at the base
Adjust contrast and line thickness to finish the drawing
