Sorry BSquirrel, I didn't take any in-progress shots on this little guy, but wampa hit it, it's a Kondo version Geara Doga.
I added extra zimmerit to his knees and rear skirt to give it some more detail. Painting wise, he was based in Tamiya Buff, then given washes of Sepia and Van Dyke Brown watercolors. Once the watercolors were dry, I used a damp brush to move them around until I was happy w/ the look. After that, I airbrushed Golden Titan Buff into the center of each panel to lightly highlight it. The rest of the weathering was done w/ pastels and then a final airbrushing of Golden Shading Gray for the smoke stains.
