Chrono Trigger Pixel Art Wall

Over my Christmas break I had begun spending way too much time in Minecraft Classic, this project shows off what I've done so far. (More will be added later.) The server that this was made on is, "The Insane Freebuild 24/7 (InsaniCraft)", on the world "SumDedGuy"

The piece in the bottom right was based off some art by a person named Lysa on deviant art.

What sprites/art should fill in the empty spaces?

EDIT: The "Epoch" was added after the video was made if you did not notice.
