That's definitely better than the first version you had up.
I hope you don't mind but i took the liberty of doing a bit of colour editing.
Since i don't have the raw, it obviously has more jpeg compression artefacts and loss of quality than yours would (shrank them down to hide some of that).

The sky IS interesting, you just have to show it off more.
There's a great colour range in there i could see while i was editing it, unfortunately i couldn't show that off since it looked terrible coming from a jpeg that doesn't have all the necessary data.
