Painting the breastplate

Hello fellow cosplay engineers, i wanted to show u good folks the beginning process of my airbrushing the front of my breastplate and pauldrons:

 I have already laid in the black and red and i am now putting in the white for highlights.

 Adding in the yellow now.

 Using this pic of a lava flow for inspiration.

 Now i have to go back into it with soem black to darken up some areas.

 Given the pauldrons some love now.
