While I like the idea, part of good thing about a white dress in a field is its glow. I feel your edit, while showing more detail, actually takes away the personality of the dress.
I agree about the glow value of a light colored dress like that for providing an ethereal feel to the shot, it works especially well in a certain situations.
This is all highly subjective, but I find the original version draws my eyes away from her face and towards the lower L part of the image. There are also the bright green weeds that are getting a little extra illumination and I find they also compete for attention. Dropping those down an EV or 2 still keeps them in the image for interest but reduces their competitiveness with the main subject, which I presume is the pretty girl under the hat and the interesting expression on her face rather than the dress she's wearing.
And that's just MY opinion.
Everyone is free to create whatever they wish that appeals to them which is one of the main things that makes photography so engaging and enjoyable.
I'm certainly no conformist to convention in many of my images either and that non-conformist approach does appeal to some viewers even more. One of the main reasons I was requested for weddings or other work was someone saw what I shot and they decided they liked it more than the usual, more formulaic and formal methods often used. There are plenty of ways to express that creativity. Have fun with it and develop whatever style you like.
