Editing software

I love my cs4. It's awesome to use for editing my pictures. There's so much to learn, so I've purchased a couple of books and asked a lot of questions. But I think I'm getting somewhere with my knowledge so far.
I took this picture from my house when a storm was approaching. I didn't like all the powerlines in the picture, so I cropped the picture and erased the rest of the powerlines. I'm thinking about making a print for my neighbor (which the tree belongs too).
