This one is complete in these two strips. The next one is considerably longer- possibly twice as long as the first. It will be a challenge to have the entire thing flow, with consistent drawings. I've noticed a tendency in other "educational" toons for the text to become just long unbroken text that's dropped into dialog balloons. The result is a text heavy uninteresting "cartoon" that doesn't invite reading or even looking. I'm thinking if text is spread out over more panels it will remain approachable, and familiar details will keep it interesting.
