SAGE Magazine Cartoon

I found this cartoon of mine recently, which was published in the first issue of Yale's environmental studies magazine, SAGE.

Personally, I've always had a hard time with the "cartoon" format. Either single-panel or 3-panel. My mind just doesn't seem to work that way, so everytime I do one, it's like pulling teeth to get concepts I like. I'm sure if I practiced more, it would come easier.
