This is a prime example of:
"when your friend asks you to make an image for their powerpoint presentation and you go slightly overboard"
This was a fun favor I did for a friend's final thesis presentation about food chains and how they are continuously affecting our bodies every single day.
I outlined the three most classic farm animals in illustrator and superimposed them according to their nutritional value (no surprise that chickens came out on top).
Then I added the fun paper effect in photoshop using different blurs, inner/outer glows and quite a bit of drop shadows. Giving the final animation.
