|Start with a basic shape for the trunk... nuthin' fancy...|
|Darken your pencil lines...|
|Suggest a little texture...|
|All you need are squiggly lines for foliage...|
|Add 'em together and it starts to look like a tree!...|
|For the area around the roots we can draw some vaque mound-like shapes...|
|...and then define the edges.|
|Remove your "mound guides"... mound-like bushes. Huh! Whatdya know?|
|Distant pines can be squiggly triangular configurations...|
|Straight lines suggest "off in the hazy distance." I lightened my pencil and used the SHIFT key to make more or less random straight lines...|
|... erase what you don't need...|
|You can use the same trick for distant mountains. Also please note I add a few hazy "off in the distance" pines to the left side of our picture.|
Remember, no intersecting lines between foreground and background. The background should always give way, suggesting distance.
This is a great exercise I'm sure you can do better than me. Give it a try!
