the image is a pretty popular one on DA and yeah, that Star Wars pic sets a pretty dark tone for Candy. 

I cannot tell between the two dark green (?) edits but so I consider them equally awesome. Maybe they are slight changes (contrast or intensity) but to me, those two look the same. 

And for the other two, as far as I am concerned, the pinkish filter definitely looks more vibrant, causing more impact to the eye. Although I must say that the brighter edit of the green ones reminds me of those dark green pixels that appear in the old video games. I also must say that the intense edit resembles a military poster from a soldier/guard because of the green´s tone that appears in a standard uniform.

Honestly, I wouldn´t have a clear preference. I guess this is up to which one convinces you the most for your next material. In general, as you say, they look pretty cool and in my opinion, I find it more difficult to pick just one. This dilemma is what I have to face before posting a few edits here.
