Hi, just read your profile and see you are asking advice to improve your work. The road and hills on this picture are exposed really well so the light looks great, but the sky was probably darker in real life than it looks on the shot?
For a shot like this you either need to use a Neutral Density Graduated Filter to balance the light and dark areas when you shoot, (that basically means it lets less light into the bright areas). The other option is to take two shots, one where you expose for the sky (so the sky looks right and the boittom half would be too dark) and one for the land (where the sky is a bit burnt out like your current shot), then merge the two in photoshop or other editing program.
Great first upload though, look forward to seeing more. You're composition is great and the colours are good which are the key things, you obviously have a natural eye for good pictures, so its just getting to know the technical side of your camera a bit which will help you improve. It takes a while and we're all still learning!
Apologies if you already know all this, but it can make a big difference to your shots if not.
