And for something completely out of left field, here's a medical science diagram! I did this by hand with Copic multiliners and Copic markers. Normally these types of illustrations are done digitally, but I have yet to add that method of rendering to my wheelhouse. So this is what I came up with.
This illustration accompanied the paper The Hemostatic Role of Factor XI published in the journal Thrombosis Research in May 2016.
