This is the foreground of the image. The focus blurs the back of the rim. Lets fix that.

This is the background of the image. I quick select the back rim and refine my edge. Ctr-J for a isolated layer. Click on the thumbnail and highlight. Copy the isolated image.

Paste the image to the foreground image. I then Ctrl-T and right click for the warp and distort to make it line up with the foreground.
