What camera and lens did you use?
This is a particularly difficult situation to shoot because of the extreme lighting difference between the sunlit background and the shaded foreground, and you've composed the frame so that it's roughly an even 50/50 split between those areas. The exposure seems to be a compromise that doesn't work for either part of the picture - what's in shade is underexposed, and what isn't is overexposed, and detail is lost everywhere.
Several possibilities come to mind.
1. Plan the shot for a different time of day when the contrast will be less.
2. Choose which part of this scene is more important to you; recompose the shot to make a split that favors the subject, and then expose for the subject. Sounds like the tree line is what you care about, so either move a little closer or point the camera down so the foreground fills more of the frame, and increase exposure so the trees have detail; in this case maybe the adjustment is to open the aperture to f/11 or f/8 leaving the rest the same.
3. Try an automatic HDR setting if your camera offers it. Personally I don't often like the effect because it ends up looking fake, but even in lighting like this it might give detail throughout the frame and color in the sky.
4. Long shot: if you took this in RAW and have photo editing experience, try "developing" the file twice at different exposure settings and blending those together using either a hand-drawn mask or a gradient line slightly above the horizon, or again, some kind of HDR plugin. Sometimes a RAW file has details that the straight-from-camera JPG lacks.
Honestly, I'd just start with #1. Some lighting situations are hostile to photography, and part of making satisfying pictures is just recognizing that and doing some planning.
Oh, and welcome to the forums!
