Looks good for a first attempt. My suggestion is to work with small areas. Sometimes if you feel like you are getting lost, it helps to work in a grid to make sure you get each area. I did this once with a very scratched photo with detailed areas, and it helped quite a bit. Lots of people look for a quick fix for problems in photos (because it is time-saving and money saving). My suggestion is to take it very slow and sample surrounding areas constantly when using healing or clone tools. Even if the areas look the same, many times they are just a shade off. Also, even with the wonderful invention of the healing brush, it still leaves a pattern or a track in some cases. I had a picture recently where the healing brush or the patch tool just wouldn't work. For some unknown reason it kept leaving artifacts. The best rule to follow is that each picture is unique and you have to somewhat relearn how the healing brush / clone tool will react with that picture.
Hope this is somewhat helpful.
