Storm/Landscape - how can this be improved?

I resurrected this image from 3 years ago a few nights ago as I know more about PP now then I did then. There were some challenges with the original that I think I may have overcome. Thanks in advance for the feedback.

I like it. Maybe add a little more saturation?

A quick try at the JPEG file... Not the best I know but, you should be able to give it some life if you still have the RAW.

I like the grass in the edit, but I prefer the ominous look of the storm in the original. I am thinking if desired, you can add more contrast to get more darks out of the clouds, but I am not even sure I would do that. Sometimes that's just what the scene looks like?

I was pondering this while out shooting this morning, interestingly enough. I looked up at the clouds behind which the sun was rising, and thought to myself, there's not much contrast in all the clouds, not much detail. If I would shoot them, I might have thought my focus is soft or that the scene looks dull ... But they really looked like that, so what can you do? That was the end of my shoot this morning, I got a few decent ones while the light was still good

do a clarify on it?

I like the photo, I think the framing is spot on, the only thing I would do is change the way the clouds look so I did this.
