Need help fixing this

My photo isn't the best representation of what the Brenizer method is, this is just the outcome of my first attempt. The Brenizer method is to allow you to have wide field of view and a shallow depth of field that would not be possilbe with just using a wide angle lens. You're supposed to lock the focus (depth of field) and lock the exposure, shoot around it, then stack the images. I believe that's how it works.

In DXO Optics Pro 8, are there filters or something that specifically say Brenizer? I'd have to check it out.
