that would help
yeah when you over expose the whites (or under expose blacks) you loose all the detail in that area permantently. if you shoot for the whites and use levels and/or curves to balance the ddarker colours you will end up with more detail and a better ballanced picture.
also what metering mode did you use? changing that may also help....
i just checked your exif and youhave the exposure bias set to +1.33 which is really high. bring it down to zero and if its under exposing too much bring it up to +0.3 or +0.7 maximium....
hope this helps
