Thanks, JT.
Well, here is the finished landmass base image. I'm sure as I work on other parts of the map this will be edited slightly but for now it is done.
I've altered some of the landmass shape, especially in the SW area. This is for two reasons: one, I wanted to get rid of the elephant shape as it looked a little too distracting and two, I wanted to alter the composition a little when the bottom part of the map is added, making that part a little more to the left than dead center.
Edit: Oh, obviously the full continent doesn't end at that straight line like that.
