First map, using Visio

[Reg06]

With this map some explanation is needed. Precipice is a home campaign set in a crapsack world- the world is going through an ice age, humanity has moved underground, everywhere is Mos Eisley, and Lovecraftian horrors abound.
So, a normal map won't do, because there is no way I am going to map the Underdark. As such locations are given with general directions and how long it takes to get there.
And as for the quality of it, this is my first attempt at creating digital media, and I only have MS Paint and Visio to use. I did all of the shapes and 90% of the coloring with Visio, and then opened the file in MS Paint to do some weathering on the lines and see what I could do with the spray tool (which, admittedly isn't much).

So, thoughts? Even if it is just "L2P noob." I'm considering going back and taking the circles off of the place names, so that everything is loose like the lake names. And I'm not a fan of all the empty space, but there isn't much to put there.
On a lark I inverted the colors, looking for a way to make the thing grayscale (which I couldn't find). I kind of like the inverted map because it is set in the Underdark.
