Very nice map. Good clean lines, nice font, rivers all good. ArcMap being used well on this one. Well done.

About the back up thing. We have had a lot of posts about losing stuff. A couple of external USB drives is the answer. Also, always save your map with a new name, like Map01.jpg, Map02.jpg etc then when your all done and really happy, delete the older ones. You never know when a file can get corrupted in some subtle way that doesnt show itself until after you have overwritten the backups with it.
