As to the reflection, yes, I should've simply used "Flip Vertical" inside the "Free Transform" tool to get the correct orientation. Regarding the artifacts introduced to the background using Content Aware Scaling, there is no easy way to repair it. What I would try is create another copy of that layer immediately above it , blur it (to minimize the artifacting), and then create a Layer Mask. Using a black brush, I would then "paint in" the glasses and table top until it looked convincing........pretty tedious work. This is the problem with Content Aware Scaling.....which is why I fell out of love with it rather quickly.

Great idea! I have added a link above the movie to get the dandelion image. Glad you found the tutorial helpful.
