Here's what I have so far for the "Shadow Out of Time" map.
Now that the overall shapes and major land features are in it's just a matter of adding details. The fine line work needed to recreate the look of a map printed off an engraved steel plate is tedious beyond belief, but the results so far are encouraging.
Update: Ack! I didn't realize that doing a low res export from Illustrator would cause such a bad case of the jaggies. Rest assured, the final map won't have that.
