My only suggestion is to apply a bit less contrast...in the second version the whites looks "hot" (too bright) and the photo loses a little of its delicate, dreamy mood.
This post is old but it show the value of woking selectively on contrast with controlling portion of image.. A magic wand tool alowing to select only the blue and dark grey to raise the contrast would have help here for a perfect result!
I think I would have used curves in Photoshop to adjust the contrast in the final image. That would allow more control over the highlights in the clouds.
