I've seen this pic many times, enough times for me to confidently state that I'm never gonna get tired of this pic. The manic and somewhat menacing expression is captured perfectly.
Imposing, but it's a natural sort of imposing. Like tornadoes and rabid badgers Bloody Will is a force of nature that carves his own path of destruction. But he also just is; stripped of pretension and unblinded by distracting forces. That sort of purity is to be admired.
Hats (or heads, as the case may be) off to you Sir.
