I do agree with the others, looks great and I wouldn't change anything.
However, to answer your question about overexposure...
IF the overexposed areas are white, meaning no data except white, there is nothing you can do, there is no data there to pull out of the image. Additionally, if the shot was taken in JPEG format, even if there was data there, not much you can do to fix it. If the shot was recorded in RAW, you may have enough data (if its not all white) to pull some detail back into the image. RAW contains more data for you to work with. Generally, RAW files are quite a lot larger than JPEG files.
