I like the composition. It has an almost pictorialist look.
I do find the dark halos to be distracting, however. It's unnatural to have the tops of trees near the skyline be jet black, while lower down the shadows are open. The premise of opening the foreground is right, just be more subtle about it. There obviously has to be a tone graduation somewhere to get the effect you want. Try to find a more natural way to blend it. Find natural borders to make transitions along, and spread the gradient out when that's not possible. Don't make the post processing visible at first glance, make the viewer wonder if you did anything at all.
P.S. Those are the Twin Sisters. The Three Sisters are in Oregon.
