Hi, Kim. I will offer you some ideas here that you might want to consider. Also, I am including an edit here, with the only purpose to better illustrate the comments, as there is not much that can be done with a small numbers of pixels. As I said on other image of yours (that one of a dragonly), just let me know if you dont like it, and I will remove it. The file you uploaded was only 960 x 640 pixels. You can increase this up to 1600 x 1000 pixels, for better display.
-Your camera was not level. This is usually a bad thing to landscapes but is easily fixed on post processed, though. I applied a 2.3 degrees counterclowise rotation to fix it.
-Time of the day/Light: Always try to shoot landscapes during golden hours (1~1,5h after sunrise and 1~1,5h before sunset). At this time, light is "horizontal" and not "vertical". This completely change your landscapes look, textures, etc. (Although you said that it was shot in the afternoon, I am not sure if during golden hour)
-The colors look a bit "washed"; looks like the day was a clouded one, so I increased contasts and saturation a little.
-Regarding composition, although it is not absolute, usually the centered horizontal line wont work great. Try to use a different approach. There is the rule of thirds for a starting point, but you can sometimes break the rule and find a new composition. Below is the composition I would consider.
I hope the above can be of some help to you.
Cheers,
