shot 4 for me, (based on composition and eye sharpness and fewest distractions) then shot 3.

Shot 3 is the most interesting shot imo and could be improved to surpass my shot 4 pick (imo ) by making that breath more prominent, cropping or cloning the brighter parts of the image at top and sharpening the eye a bit more (if it can handle it).
Hope that helps - Marko
