One of my relatives has a digital camera and he used to use it a lot. I just took some of his pictures for wallpapers. But they are not sharp\colorful etc enough. Since I am a total noob at GIMP or art in general, and some of you are seem to be a pro I thought I ask some advice. Below you can see an example. How can I make it look better?
Edit: oh great the pic is too large, ~892 KB. So you can't see it yet. What's the size limit?
