Its not a bad image at all. I think though you cropped it too tight. Also, its quite washed out, i mean the colors are not very vivid. I would try to add more contrast and saturation to it to give it more pop, and some sharpening.
I like the curve of the mountains, it really seems to draw the eye into
the picture, I would agree with a little bit of contrast/saturation boost,
but a good effort, I think landscapes are one of the hardest genres to
take.
