This is one of the 3 pieces of art I'm deciding to upload, that I did for my final art examination last year.

There were all free hand drawing with a reference that I had off to the side, no tracing was involved.

I came up with this idea;

Batteries of the Animal Kingdom.

Basically the lower the level of charge in the animal, the closer it is to extinction.

Copy pasta-ing this info to each post, just so you know. =3
