Quick Scribbly Trees

Done as part of a practice session of 30 seconds in length. Current goal: Draw my one-point perspective, in my backgrounds, scenes, and environments, with most, most, and most instinct, and most, most, and most feeling. Now keep in mind that they don't really look like trees, but what gestures they make, and why they make them that way, and how they make them. What do you think???
