The guys are right that this is the best of the lot, but I think that is kind of a given, seeing how you say you weren't quite happy with the various earlier versions.
It's very fascinating to see the artistic process behind this image. It still looks more like a (gorgeously painted) comic cover than a movie poster (most visible with the hair imo, and perhaps inevitable with your slightly cartoonish art style), but the detail and the desaturated colours really make it something special.
