Thanks folks,
Finally figured out a color scheme for Brutus:

I kind of flip flopped the armor colors and I think it works good. I plan to lighten up the grey to a near white and pink/flesh in spots. With the brown I have a good color to work up to NMM gold or bronze or even rusty steel and a good color to work up to flesh with as well. The armor has some mouths and eyes sunk into it so I am looking forward to playing with NMM melting into skin.
I had nearly 3 solid hours to paint today! I forgot how much work it can be to stay focused

also it really made me take note of how heavily I lean on my airbrush. Not necessarily a bad thing but I don't want to slip into complacency.
To shade the armor and do my black lining I used these with a little matte varnish:

I have been raiding the art supplies ever since the dragon dio and these have been in the back of a drawer for several years. I feel like we used to call them India Ink in school but I am not sure if that is correct. They are amazingly dark without being opaque and have a very thin consistency that seeks out cracks and crannies. Without any matte medium added, you can go back in after they are dry, re wet them and move them around clean or clean them up. Not sure how long that lasts but might be very useful down the line. With matte medium added they are a little more predictable and don't run everywhere or pool. Hopefully they are stable on the mini (!)
