While my previous map isn't quite PERFECT yet, it's going to be a while before I get enough feedback and circulation for it to be ready for a new version, so in the meantime I decided to finally start a map idea I've had in my head ever since they announced Sawmill for the Sniper Update. My problem is that I just have absolutely no idea where I should start in creating this. I have an idea for the CONCEPT, but I don't know exactly how I should go about mapping out the actual map content. I have a clear vision for the start and end of the map, but I don't really know how to fill in the blanks, or even where I should begin in constructing this. So I ask: where do YOU start with mapping?
