That's a good start. I'd agree with Rhotherian's suggestions. You have to ask your self what you are trying to convey with the map. If it is a collection of information that will help you write adventures and history for your setting or is it something you wish to be more "artsy" with depictions of mountains and rivers and other features. Maps can become very crowded very fast as information is added to them. You might want to consider doing a few versions of the map if you think your going to "overcrowd" it. I wish you success and keep up the good work !!
