Your off to a great start!
I don't want to bombard you with too much so I'll start off slow and I'll develop my concepts as you respond.
1. See how the foreground and middle ground are the small value? To create more depth lighten the background. Which leads me to my next point
2. Just over the hill in the bg the fog stops abruptly, as if there is an invisible wall it cant get past. This artificial line doesn't help the composition. If you soften the hill line by adding fog pouring over it (like you did just below) your eyes will gravitate to the house which is the focal point.
Just wanted to reiterate that you did a good good over all. The detail in the foreground and the smaller fence posts both help to give perspective.
