A whole lotta railings!! 31 to be exact.
Sprayed black first. Then drybrushed dawnstone, then all detail painted. Then a light highlight drybrush of screaming skull.
Yellow was done with Averland yellow (the base one) and freestyling the black lines.
The hazards were weathered with Averland yellow in thin lines. Then the edges were chipped with a mix of Black, 2 parts Dryad bark and 1 part Warplock Bronze.
Then a whole pot of Lahmian with two blobs of Mournfang Brown mixed in (shaken). Was painted on and wiped off straight away with kitchen roll to allow the grime/Rust effect to remain in recesses.
