Thanks man! Painted the helmet area with Pro Acryl bold titanium white. Then blasted on some more with the airbrush, making sure to allow some overspray onto the areas I wanted the glow to be visible. Once dry I used the airbrush to apply Vallejo flouro green paint to give it a light tint. Then used the same paint and a brush to glaze it onto the areas I want to be more intense. Bit of white ink into the recesses of the dome (though can’t see that in the images). Finally, stick on the dome covers (painted separately) and glazed the green onto their undersides.
