I used a 20cm wooden base and covered it in a fine grain sand paper. I then made that look like a road. I then used woodland scenics foliage to create the side of the road. After that I then customized some of the figures from their base paint job as shown in the image.

Ironman is 100% custom where Captain America only his face and his shield is painted.
Titanium man is customized entirely and the Wheel barrow is also entirely painted and weathered.
