Critique - Earth Day art

The earth day story in short talk was a "tips to tack" story, which in the past has been designed as a plain piece of paper (usually grey) with a grey tack holding it up. Since we now have the use of color, I thought I would make it look more like notebook paper and use a colored tack. Following this theme, I wanted the illustrations to look like someone had doodled on the paper. I'm afraid my doodles look more like sketches than actual doodles, though. Perhaps there should be more non-content driven doodles, like random geometric patterns or scribbles that one might find in their notebooks. I didn't want to distract readers from the content, though, so I stuck with mainly content-driven doodles. I scanned in my drawings/doodles and used photoshop to compile the notebook paper with the doodles. I was pretty happy that this art, plus the paper cutouts I used for the hemp story, break out of the practice of using illustrator to create the art. It's fun to experiment with different styles and media for the illustrations.
