At this point, I was rolling right along with the painting and completely neglected taking any more progress shots! I need to figure out how to remind myself about this - for now, I'll just tell myself that I was lost in the joy of painting!!!
My next step was to drybrush the tanks with the base color, and then a lighter version of the same color (I just added some white).
Next, I painted on the black camo, and highlighted it with a quick drybrush (I added the base tan to my black for the drybrush). I used the thinned black paint to paint the tracks at this point as well. When I had the tracks painted and dry, I thinned the paint some more and sloshed it all over the roadwheels and sprockets.
I mixed orange and black for a dirty rust color, and painted that on the exhaust pipes. I originally painted the boxes (mufflers?) that the pipes attach to orange as well, but a little looking showed me that no one else seems to be doing this…. I can only assume they aren't mufflers - or they just don't get very rusty! After a quick paint-over on the muffler/things, I was back on track.
The tanks were essentially done at this point - only the tank commander and markings needed to be added/finished. I decided they looked a bit too neat and some things weren't well enough defined, though, so I thinned my black even more, added some brown ink, and gave the tanks a nice wash to deepen the shadows and dirty them up some.
I quickly painted the tank commander and markings, and these tanks were ready to roll!
