This was back last year. I took a EG RX-78-2 and used hobby mio lacquer paints through my new iwata airbrush. Overall pretty happy. Used knight gold and mecha “black” plus red on the eyes. Only complaint was the black was purple. Idk who at hobby mio decided THIS was “mecha black”
I think the colors compliment each other nicely. Well done! As someone else mentioned, pure black tends to lose details.
