I messed around with some textures after I got home from work...
And after adjusting some opacity on the earth texture...
I think for my purposes I'm going to call this a finished map. Next up is to delete all but the base outline layer and the earth texture, offset the the base layer to move the gorge to the left side of the image, and work on the upper deck for the second encounter. Shouldn't be too hard now that I have a clue.
