Thanks for the kind comments, Charles. The perspective is impossible, as you point out, including a variant on a drawing of three cubes by Reutersvard. It's too bad that the small file size on the site precludes the finer detail from appearing (the shapes on the leaves of the tree, for example).
Asher, the undoctored scanned photo from which the wooden structure was made is below.
I cropped it, combined six perspectives symmetrically to make a tower with roof, and proceeded from there. The background tree and foreground are from the same vicinity as the wooden grain elevator that was undergoing demolition. A lady called Eve with the demolition company told me the elevator dated from 1878 and another demolition worker said that some of the wooden beams still wept. Maybe the building wept for its own demise or because of the ending of an era. Hence the 'enchanted' childrens' story book framework and coloring. But no prince will come to kiss that era to life again.
