Great little tutorial, working through this and the regional map one of yours RobA. I am how ever running in to issues with the mountain making. Not sure why but every time I try to make a mountain i end up with a halo around the range. It's obviously from the early steps where we use a gaussian blur on the first layer but I just can not seem to replicate your results. I will try again in the morning on a fresh map and post my results.
