It's finally here! Welcome to Isometric Hills, wooooo! I've done a lot of Iso Mountains and Volcanoes and some Canyons, but until we had not wee little hills. So here ya go. I did some quick (rough) sample of hills next to mountains, but they also work glorious in plains and grasslands where you'd have kills and no mountains. You could probably use some for sand dunes as well. Some are more rocky/harsh, others are softer and more bubbly.
