Early interior design for Izzy's house

Early exteriordesign for Izzy's house

There was a museum at one point in the story. These are some thumbnail explorations for it.

The museum had a big tree around. This are some explorations of the silhouette and relationship between the two

And there was a X-Ray scan at the museum, a security check to detect Non-Unicorns

Some very early exploration for architectural styles in the Unicorn forest (called Everfree at some point)

There also was a palace (later a museum, later a tea shop)
