Generally the brush isn't important, I think your problem lies in in your understanding of values (scale of dark to light).
Metal has a very high contrast and reflectivity, try turning your reference to greyscale and also your study and compare the values. The armour is very shiny (very high lights on the value scale) and reflecting the enviro and colours around it. Try also squinting your eyes at the ref to catch the value shifts and the value range and do the same with your image and you'll start to see where to make lighter etc.
