This is going to be a awesome challenge. After seeing some of these maps, its going to be great seeing what everyone does with the same islands(particular the island I chose, lol). Rivers, mountains, etc. Who puts the valleys here and why, then throw in the different styles. Going to be fun.
On second thought, My 1st, 2nd , 3rd, ...10th attempt on mountains came out too realistic for my watercolor approach. This is not going to be fun.
But I have an image in my head, I will get it to paper, then to Gimp, then through a filter, then another, then a bump map, followed by a blur, then overlay, then back to normal, and with luck it will look just like my 1st attempt at the mountains, that I decided not to go with.
