Nice first post map ! Its finished off very well with that border. You ought to enter some of the lite challenges as I think you would do well.

People like the fluff and background to a map - I know I do. I think if your doing a big project or making up a WIP thread to a map then posting some of that at the start can help people get into what your doing as well.

I was going to mention the rivers too but Gidde has beat me to it. In this particular map it looks like something special is going on at that location that may justify it but in general things like this don't occur. There are a few selected instances where a river splits but its amazingly uncommon.
