Pretty!

I love a good backlight glow on a horse, but it may be too bright/needs to fade out a little more to make it appear more blended.

If possible, maybe a little bit different blend on that ground hoof; it looks like the hoof just poofed below the coronet band.

I agree with Raindrop, the bridle is a bit too bright. I had difficulty deciphering that it was a bridle due to the head angle, so perhaps some sort of defined lines are needed.

I would also edit out the bridle or lower the brightness. It took me a few seconds and a zoom in to actually realize that it was a bridle.

The edges of the horse also looks quite blurry. I would sharpen the horse up a bit. I would also sharpen the background. When I zoom in on the footing of the horse, the "front" of the background is just as blurry as the "back" of the background. Because of this reason, the splash on the footing looks too sharp and out of place compared to the rest of the background. I would sharpen the front of the background and slightly blur the splash to get them to match.

I hope this makes sense. :) If you need clarification - feel free to mail me. I can be a bit confusing at times lol!
