It’s probably best to view you tube videos to see how to edit with Lightroom. See also the page at the top called ‘Editing photos’ to find some more tutorials.
I just wanted to show you how it was possible to completely change an image with this software. Mind you, I’m not saying this is a good photo or the editing is any good, but I’ve just been playing around to show you a very small sample of what you can do. The editing tool I was trying to master was the graduating tool. (Who says you need filters!)
