Many elements here for a good post card, but I think a little more detail in the foreground would improve the image. The horizon is tilted just a little & you can illiminate that pixilated sky by running it through NEATIMAGE. You can download a trial version on their site. I've have lots of pictures ruined because of that problem sky. I like the colors in this, it looks almost like a water color. You've made some nice additions to your porfolio since I last saw it.
