Thanks for the feedback guys, its actually not so dull in real life, my photo skills and lighting are terrible, which Im trying to work on.
Once I get around to building a proper lighting area, I will repost this model for further feedback. :)
I'm not sure I agree with other comment. Get your self some mig pigments and dirty this bad boy up.I'm thinking mud and dust on the lower half and rust on the pipes and metal work.
