Have done some work since my previous post, though it's still very much WIP.
The texture is a placeholder for now, though I may integrate it a bit more. It needs some variation, which is why I've added some more trees, rivers and a large lake/ocean. I will be adding roads and towns/cities so that will fill a lot of the blank spaces, but I still think it needs something extra. The sea will likely get some work done on it as well, though it is highly probable it won't be much more than a cloud-generated overlay texture. PSD file is reaching 800MB, I may have to do the cities and such on a seperate file that holds just the landmass and geography assets. Any comments more than welcome!
