I believe that Bly is finished. I added some suttle weathering to him by drybrushing some dark brown onto his boots, legs, arms, torso, and just a hint on his helmet. I wasn't going for the muddy look here or anything and just made him less shiny like Logan had suggested.
I dug out a large legacy rifle for him and drilled out the barrel, painted the stock dark brown, and then drybrushed the rifle with light ghost grey paint.
