Taking into account what the others have already said, sound advice. You have got a good exposure there and i like the composition also.
So its really only a question of processing and you will see a whole host of styles here. I think this forum is a great learning place and a great place to study other peoples styles. Some will keep there processing methods close to there chest, a closely guarded secret others will be happy to share so if you see something you like don't be scared to ask!
You will find some obvious things to look for in your shot which can be artifacts from processing, so you will find pushing this or that slider too far will cause a particular problem.
Anyhow maybe the HDR software you used may have lifted the foreground too much, it has a tendency to do that! The greens do look a little electric but this could all be as a result of the automated HDR...
I don't think the grass adds too much to the shot in the foreground and if you scroll down/up you can see what the shot looks like slightly cropped with just an "edge" of grass (small strip) of grass before the edge. Alternatively i'd probably drop the exposure by a big handful on the grass and check the saturation after you have lowered the exposure on it. Then look at the haloing then your sorted. Is the flare present in both exposures btw?
I love the cloud and the colour in the sky BTW.
Time you have climbed up there a few dozen times you'll have a great circulation, and i don't want to spoil that for you and tell you the easy way
