I made another War Phoenix mini and did it in desert camo to match its sister 'Mech; this time I used a different method to get the panel lines as well as changed my photo setup to limit the brightness. The Nuln Oil wash and the Tamiya panel lining is shiny, and it reflects light despite being black - so all my lining was washing out in the camera. This one was painted normally with Tamiya acrylics, then I went after the panel lines with black Panel Line Accent Color. Some touchup painting was necessary afterward, but it's a lot darker and more filled in than the Nuln Oil.
It's also a lot more time consuming and difficult, I haven't decided how I'm going to paint up the rest of the 'Mechs for the Devil's Dozen.
