TinkerLabSketchbook Challenge, 5 April 2014

I'm participating this month in the TinkerLab TinkerSketch Sketchbook Challenge. (I'm not on Instagram, but will share on Facebook and Twitter.) The prompt for April 5 is "Magazine Collage."

 

Publications used for this digital magazine collage include Kexue Dazhong (from this cover), National Geographic (original image here), Popular Science (this cover), Science (covers here and here), and Sierra Club (original image here).
