Photo Fix of the Day

Here's a photo I took at a local farm this past week. The skies were dramatic all day and at one point I spun around to see these intense rays of sunlight pouring through the clouds. When I first processed the photo the juvenile apple trees in the foreground were very dark so I brought up their exposure quite a bit. I added some clarity to the clouds but other than that I didn't do much. 

How would you improve this photo? I thought maybe some cropping would have been in order but I opted not to. What do you think?

I shot this with a Sony NEX-7 using the kit lens at 21mm, f/8, ISO 100.
