Spent some time on a program by the name of WorldPainter, and with a bit of work I managed to figure out how to use it and make (in my opinion) a pretty nice landscape. In the pictures shown I use the texture pack John Smith. Please show all your friends and diamond if you think I did well! Feel free to play around on the map, but give me credit if you use on YouTube or any other social media sites (not sure why you would). I also recommend downloading and trying WorldPainter as it is one of the best programs to use to create 2.5D landscapes.
