Ruins

Here's some terrain I made for ca 2 months ago,
what do you think? :P

nice

Sunken ruins tileset is teh best. I suggest to give more terrain deformation in order to achieve a more ruined feeling.

I think the waterways are a bit too unnatural. Make them wider / thinner in different areas, and use the 'Lower' tool to make them appear deeper in spots. It also adds a nice effect.

The angle in the last one isn't great. The third one you can see the edge of the world, and I think you should see something in the background, like mountains or a temple.
