I am genuinely intrigued. The front appears as broad daylight, the background as deep twilight? I know deep shadows in daylight are bluish (hence the UV filters), but I do not ever remember that intensely blue.
Now, do not get me wrong, I visually prefer #1 version (with a tweak or two), very graphic, even if lacking in believability. The third one, as much as it might be natural, is... lifeless.
