Here are some terrace tiles I've made. There should be a lot of variety in what you can make with them and I've given a small example.
The tree and bush tiles are on my other sheet here: magiscarf.deviantart.com/art/B…
Edit: Made another version without grass and some other things. Also, the rocky hills can also be found on the above link to my other tiles.
