Current Flag:
This flag does a bad job of representing the state, but like a few others, there is a good flag within it. South Dakota is unofficially known as “The Sunshine State.” There are, seemingly, rays of sun coming out of the seal. I think a sun would make a great flag.
My Redesign:
There we go! The sun represents “The Sunshine State,” and the circle is a replacement for the circle of text on the original flag, which I thought made the flag a little more interesting geometrically.
