I like the backlighting and the mood and the story it tells. The silhouette of the birds on the right and the partial silhouette of the main subjects works, and the glow around the rim of feathers is nice. I guess I would clone away some of the stray grasses seeking a cleaner look without disrupting the vibe.
One distracting thing to me is the blown out areas within the main grasses. The blown out sky adds to the feeling, but if the raw has anything to give to selectively pull down those blown out spots near the subjects. It's nice that they are bright, just need some detail. They kind of pop out as negative space becoming positive. That might be a job for photoshop but you could try it in curves to pull back the whites in that area only.
Nice shot overall!
