Wanted to make this look ironlike & heavy. Hence the 'stonelike' appearance. Base is Blue-ish Grey to conjure up a feeling of a cold & lifeless Planet.
Comments & criticisms needed.
Nice model, but there is room for improvement; the mini is low on contrast with armor and metals merging together; there is also a lack of focal points, everything is muted and a bit, well, boring. Shoulder symbol and base look very neat though.
