I am starting to realize how in camera composition is so key. While there is a lot you can do in post-processing, you can loose some strength in the image if you leave it to later. If you look at the picture below, you will notice that my alignment with the sign/horizon is off. If I had noticed it while looking through the viewfinder, I could have easily leveled off the sign edge so that it was parallel with the bottom of the frame. When I completed editing the image, I had to crop out some of the plane and sign. While I still really like the shot, I would have liked a little more of the plane and the sign. The final image is above and the un-cropped image is below.
On a side note, I took this picture while watching planes land with my kids. I focused on the sign so that the plane would be out of focus in the background. The big win with this is it was my second composition. I was able to see where the shots might come from before I took them. I only took 4 shots of the plane, with the second one being the one to keep. The overall goal is to take less shots, more of which are worth keeping.
