Adrenal Gland page 1 and 2

Part of a huge project to design how each of the Tyranid biomorphs work. I'm planning on making a flash book and publishing on the web in the style of an Inquisitor's handbook once I am finished. This is currently only a test of what it will look like. When I come to publish it I will use only my own images.

Drawings done in pencil.
