How does color please your eye?

I seem to be drawn to warm colors.  I am finding as I play in photoshop I enjoy warming up my photos.  I think that's how you develop your style.  The blogs that I like the most have the warmest colors.  I need to print my pictures one of these days to see if I have taken it too far.  I wonder if the computer screen and printed images have a different look.  Here is one picture that I played with 3 different ways. Trying to enhance the colors of the grass and Caroline's skin in different ways.

First one is the original.  Followed by a skin and light enhancement.  Then I only adjusted the saturation of green in the picture.  The last is a color curves action that does all the work for me.
