I really like this! and goes to show that you don't need the latest gear!!
I love a nice misty shot but for me there is no compositional value in this shot, to much sky, to much grass. There is a nice bit in the picture that you could've got by walking forward a bit. I hope you don't mind but I've cropped you're image to show you what I mean, you could even crop it tighter to the thinner trees on the right. Cheers.
