Lightly sketch an oval to block in the shape of the maple leaf. Add 5 vein lines extending out beyond the oval.
Connect the top of the vein lines with an inward sweeping arched line that touches the initial oval. Draw in the stem down and away from the leaf.
To the right of the maple leaf, block in the oak tree leaf by drawing in the center vein. On each of the lobes draw in the curves and the points. Add the stem on the opposite side of the leaf.
Sketch in the third oval-shaped leaf by following the shape of the actual object. Draw wavy lines where the leaf is wavy and crinkled. Draw in the center vein line. Add the stem toward the bottom of the leaf.
Using a soft pencil, draw over the vein lines again on all three leaves making them more pronounced and adding several more vein lines which appear on the leaves.
Shade in the darker areas of the leaves, primarily around the edges and where there are bumps and dips. Push more lightly on your pencil while shading to gradually transition the value to light gray or white highlights.
Shade in one side of the stems.
Use an eraser to erase any pencil lines or shading outside the leaves.
