Nice lens.
I like the spontaneous captures, it really brings out the mood.
Few tips though:
1. Ease up on the sharpening, it's loaded with halos. Maybe you're using a fuzzy CRT and you can't really see them, but on my screen, they're glaringly prominent.
2. While you tried to increase the detail with low radius USM, try a bit of high radii sharpening to create contrast. This will give a greater sense of sharpness rather than having detail.
3. Face is in the shadow. One technique I use to bring out the lighting in faces is to use the history brush, select the most current history state, and change the blending mode to screen. Set the opacity to taste, and paint over her skin. I find this technique effective in mimicking studio lighting.
4. This is a personal taste. But for these dramatic wide angle sky shots, I like to add a bit of vignetting to make it feel even more dramatic. To add the vignetting, I like to use the gradient tool, and set the blending mode to overlay. Choose the black to transparent gradient, and reverse it. Choose her face as her starting point, and drag it out off the canvas.
