Rest assured, I have a release coming tomorrow (the 2nd of April!). I would have had them out on the 1st but I ran into some issues with the newest update of the software that I use that set me back a good ways.
I've had a lot of request for "hills", and this was the best I could get. But after doing a lot of Google Earth research, this is actually how hills look from above. Should be able to surround larger mountain ranges with, or simply have some hilly-but-not-quite-mountain biomes :)
Anywho, here's a couple samples of from the pack. I just quickly colored theses, but they will, like most of my assets, come as transparent png files and PhotoShop brush packs!
