that was fast - but I'd like to give you one more tip
Instead of using an off-site service - press "go advanced" and use the uploader here on the guild. That way if your hosting site should ever dissapear or be down, the forum will still have access to your maps. In addition to that, the system will automatically make a thumb of your map
And I've looked at your map and you got a good start, if you throw in some city/etc names and perhaps a legend it will help understanding what we see
