First off...Welcome Aboard!
Secondly...since you posted a map in your intro post have a bit of what we here call 'rep' *bonk* (its really just a way of letting folks now that you appreciate/like/enjoy their work, etc.)
I took the liberty of editing your post and re-uploading your image to utlize the 'preview' function built into the boards. That way it doesn't take up so much space.
Now on to the map... It's very interesting, with the color scheme it really looks more volcanic or demonic than arid/desert like. Was that intentional?
