So this Noise Marine idea is based of course on it's classic miniature, and Doof Warrior from Mad Max movie. Which is perfect combination I think. It took me about 50 hours to finish
Doof Marine
Decided to give him a little bit of "clown look" which may be for some people creepy, and for other similar to the "clown world" philosophy which seems to be accurate in case of Chaos Marines, for me at least.
Behind him is Sonic Dreadnought. I wanted it to look massive, at least. Role of this Dreadnought is basically to add more Noise to the battlefield, while serving as Sound System for Marine's weapon of choice- combi bolter-guitar-honk.
