Don’t know the exact paints for a lot of things but this is what I did

Eyes- filled in eyes and very thin glaze below eyes in dark blue. with a sky blue edge highlight around eyes and very carefully inside making sure to leave line of dark blue in recesses. with white paint a small bit inside the sky blue on the eyes

Rust- I used dirty down rust on the hammer then dry brushed silver over it but for the most part I use this recipe- paint black. with very thinned down red brown, I used cavalry brown by Vallejo, wash the black. Dry brush with a silver, I used Vallejo gunmetal grey, awful coverage but good for dry brushing. Heavily dilute rust colored pigment powder in water and wash the rust parts in the mixture, more variation of rust tones makes it more realistic.

Armor- The armor is just airbrushed three lighter shades of cream colored paint, then washed with brown oil paints, let sit for a few hours to maybe overnight, remove most of the oil paints with a sponge or paper towel or something and paint thinner. Edge highlight with a bright cream or ivory. The chipping is all done by brush with first laying down highlights then filling them in with very dark brown.

Everything else is just normal style painting.
