So after being inspired by DezartFox’s World Eater Rhinos I started painting my heavy sentinels with a streaky red pattern. I quickly decided to modify the color scheme a bit to fit better with the rest of my army and started painting a fade to yellow to match my commander’s cape.
After painting the red/yellow with the large dry brush, I repainted the metal parts black before adding silver and soon the brass. As the first deadline for the ToEMP hasn’t yet passed, 73rd hasn’t released the details on the second challenge yet, so I am not sure if these sentinels will yet fulfill the requirements. If not, well I still have plenty of other models to get done.
