very awesome process! i do have to admit that i personally like the 4th and 5th rendering most. Since there are not that many details, the accent is more on the pose and the feeling that it gives off, instead of the light that flashes everywhere. Sometimes less is more But I love your artwork alltogether; It's a stunning result! Keep up the good work
I actually prefer the 5th rendering, despite its lack of contrast and dramatic lighting, it has a more ominous coloration, and I prefer the hair going left as opposed to right. The balance is better in the final.
