What should be included in the thesis of a descriptive essay?

There are several things that should be included in your thesis. The most important being, a brief description proving or disproving your theory (or what your trying to prove). The next thing you should probably include, is your own personal viewpoint, and how it relates to your topic. But make sure you don't make it two personal, the readers should not become distracted from the main point.
