Alright! So, as you can see, this is somewhat of an evolution on a previous map of mine. I finally managed to create mountains I am somewhat content with. (with help from isomage, for which I am quite grateful!)
I have now moved on to worrying horribly over borders, so I'm making progress. I put the borders on this map just as a quick example to demonstrate my singular somewhat poor idea for them. I'm not quite sure what to do for them.
I will update this when (or if!) I make further progress.
I would appreciate any and all comments or suggestions any of you have to offer.
