This Dreadnought is from my own Space Marine Chapter. The cloth around his legs and the scroll hanging from his arm were done with greenstuff. The picture does not show all of the finer detail in the paint scheme, unfortunately.
This was Basecoated in white. It had dried with smaill grooves adding a more weathered look to the overall scheme. Again my camera does not do this dreadnought justice. I also painted spots where the paint looks like it has worn away over the years and the metal shows through. Some heat spots on the back and gun, etc...
