Re-shooting previous images in your collection can be an excellent way to improve your skills. Over time, you will gain an understanding of how images can be improved based on your own learning and feedback you get from others.
Landscapes are difficult images to compose... You have to find a way to connect your viewer with a scene that they aren't familiar with. This image doesn't seem to have that connection point and there is no particular subject element that draws me in as an outsider to your scene. The time of day that this photo was shot doesn't lend itself very well to intriguing lighting. Most of the interesting detail in this scene appears to be in the shadows... Maybe an alternative perspective and time of day could be chosen to create something more magical about this scape...
