Chris, the way you do metal is awesome. The damage and rust is incredibly realistic, particularly on the hazard striped parts. Ever thought of doing a tutorial?
Nice job! The weathering definitely looks great. Nice scratches, damage, rust, dust. Great looking tank.
Chris, this is a beauty! is it coming to blog wars?
I second everything Alex and Greg say, plus add the OSL blue really pops and lifts an otherwise (great) dull metal and dirt paintjob. Love it.
