Catching Up: Concealed and organ crew

I'm catching up on posting Inktober drawings by posting these 2 together. I used prompts from Janelle Shane's A.I.nktober: A neural net creates drawing prompts and the associated bonus material.

22nd Inktober drawing prompt: Concealed

23rd Inktober drawing prompt: organ crew
Looks like Brain is too cool for the group portrait.
