For a natrual you're about as good as it gets. Big, cut, and looking fucking STRONG! Great work, keep it up!
However, with the great progress you've made i think its time for you consider the needle. You are obviously built for bodybuilding. Why not give it a shot? Genetics like yours don't come along everyday [ask Adonis, Buttsuck and Squadfather], so why not 'maximise' your potential?
