I think for GM-mapping purposes, your map works fine. Its easy to see where things are located and elevation and so forth shows nicely. The map Mark presents is more like a "teaser" for the players - an overview from a tower or hill outside the forest. Once they enter - they should map them selves and you should keep track of where they actually are going instead of where they think they are going *lol* - although Im guessing with a wild elf ranger - they probably won't have problems finding their way
