I love the original. The color of the grass is a little understated but it allows the model's skin to glow a bit and draw the eye to her. I also like action two very much because the dandilion gets more notice without the color to distract from it. Action 2 has a more nostalgic and daydream like feel to it. Also action2 really showcases the expression on her face so I can more easily connect with the overall feeling of the composition.
Hi I think that the Original is a great shot in itself, my least favourite is probably action 3 although it does highlight the picture very well, I like what you've done with the colouring on action 1 and action 2 has a very silent movie feel to it but I feel it loses some of its emphasis because in contrast to the others the contrast is much less obvious. I think the best of these four pieces is either the Original or Action 1.
