Dear Intikam,
Please dazzle us with your brilliance.
Your "shape 4" is labeled as being "the nearest shape to be real".
The alleged ice wall around the perimeter looks to be at an elevation of X.
The alleged north pole also looks to be at an elevation of X.
The line of latitude which is approximately 20 degrees south of the equator looks to be the lowest elevation which we will call Y.
All other degrees of latitude are at some elevation less than X.
All of the continents are positioned at some degree of latitude less than X.
With this in mind it seems that, unless FE magic is used, a good portion of the southern part of North America, a good portion of the northern part of South America, most (if not all) of Australia and the central portion of Africa would be completely submerged.
The part which I'm hoping you can bedazzled us on is, with "the nearest shape to real" being a tub (or bucket if you wish) what is keeping the waters of the oceans from inundating all of the land which is at the lowest elevations?
