Interesting design with great colours. I'm not sure if I like it, but it's definitely unusual and intriguing. If it is candy, somebody seems to have eaten an awful lot of it already!
I see a sketchy areal view of a many storied building with an enormous ballroom with rooms above and beyond and, maybe below. We can see only parts of the design - the spiral staircases connecting each floor at the floor corners, hints of bannisters and major central features. But either this is a view of ruins or it is a half finished copy or plan of the structure. Great fun to imagine what else would be in such a colourful place!
