I'm going to stick my neck out a bit Christina, and based on my own frustration with epic scenes like this that just don't come out looking like what I thought I saw, I'll try (with Foot-in-Mouth disease) to bring your image closer to what you may have seen.
When I run into this issue it is so very frustrating that the camera doesn't seem to capture what I saw and the emotions that came with that experience. When I try to correct for the shortcoming in post processing I have to rely on my poor memory for image aspects like color, contrast, vibrancy, and so on. Sometimes the viewers will comment that the result is too much this or that. In the end, it is what I feel "I" saw that I'm trying to recapture. With that in mind, I'll offer some suggestions for techniques you can apply to a situation like this. If nothing else, perhaps it will provide you with some tools to experiment with.
When I start an experiment like this I'm not as concerned about perfection as I am in finding a way to move in the right direction and in that respect, the more difficult the image is, the more I can learn from it. As they say, "A smooth sea, a skillful mariner never made".
As I'm working from a post processing perspective and my goal is to learn how to improve that image that is available, I'll leave the reshoot comments to others at this point and start with the processed image you posted.
You said that for you, "the photo was about the dramatic sky".
How do we add drama to a sky? Without worrying for the moment whether or not the result is realistic, we can warm the image (as others have suggested) to make the clouds come toward you (cool colors tend to recede). On the easiest ways I've found to get an delicately effective warming is to use the Brilliant Warm preset in Topaz Labs 'Adjust'. Another easy way is to use the Overlay Layer - make a copy of the image and in the Layers panel click on the dropdown that shows the Normal layer and choose Overlay. The neat thing about the Layers panel is that you can control from 0 to 100% the amount of effect the option can provide. This version of your image is at 100% but that can easily be dialed back to suit your tastes.
In this version I also lighted the foreground and applied a touch of Local Contrast Enhancement with Dodge and Burn to bring back a bit of detail so as to help offset the massive sky.
I didn't want to crop the image and loose any of the blue at the top, but for a landscape, the current narrow aspect ratio feels confining to me. As an alternative, I used Free Transform to stretch the Aspect Ratio to approximately 16x9. For some images, any compression or stretching can be a disaster but a scene like this can usually handle it fairly well as nothing feels odd about the wider view. By applying these two basic changes we end up with something that has moved in this general direction.
Hopefully it moves the image in the direction of what you saw that morning?
