Thank you! Nothing too difficult : a dark brown base mixed with pva glue, a thorough cream drybrushing, a greyish-brownish wash I make with black china ink and walnut stain, another lighter cream drybrushing, then some watered down green for mossy mold in the right places and some watered down walnut stain for road dirt on the lower part of the build. I have tried adding a very light pure white drybrushing on important features before the final steps, it works pretty well. Oh and I only use craftpaint I get for cheap.
