This package comes with two great maps optimized for MapTool and other VTTs along with some brief instructions on their use. I brought up MapTool and quickly dropped the maps, added a few tokens, and was ready to go.
The maps themselves have rich textures and are nicely detailed. One scene is of a desert oasis complete with trees and other terrain to make battles interesting. The other features rocky outcroppings and a huge skeleton that would make for a great ambush spot.
I have two suggestions for improvement:
1) include a few tile-able textures that blend in well with the maps so the GM can easily set a blendable background
2) distribute a .rpmap file (exported from MapTool) to make importing the maps even easier. This becomes more important when you add things like line of sight restriction.
