Design Sections of the body

There are some sections inside the monsters' body. My job is to design those sections and think about different problems which the main characters would deal with.

Those small creatures (we finally decided to call them SPs - stand for Special Parasites)will  go through different part of the body. And for each section, they will encounter different environments and against with different aliens.

  -For example, in stomach, SPs will meet their enemies from the above holes where keep dropping food and aliens.

Basically, I divided the body into 4 main sections, here are some images i have composed to show these scenes.

STOMACH 

 

HEART
