An Ultima style game is a fantastic use for tile styled like these.

When you say include a demo scene do you mean like a demo image? If so, I fully agree, not sure why I haven't been doing that with all of my asset packs.

"a demo image" : exactly, It will help everyone to figure out how tiles fit together.
