I really like your paint job, here. I think the fire looks great; you went with a more ethereal flame than a realistic one, and it's successful, imo. I like that you've removed the brazers and substituted detached torches. The way you've painted the wooden beam he's strapped to is striking to me. It pops. Most of the metal you've painted is well-done.
His skirt-deal is great. The contrast you've achieved with blood soaked middle sandwiched by the lighter top and bottom keeps my eyes moving. There is good blending on the skin; I don't see any glaring brush strokes.
Great job. I'm painting this crew, now, and I will be using aspects of yours as a reference point.
