Still a rather noticeable difference.
Now make your canvas size much larger, then select the image layer (if its locked, dupcliate it) and then ctrl+t to transform. Right click -> warp, distort, perspective (whichever you prefer, use a mix of them all) and nudge ti around until it looks perfect. Draw some lines using the line tool (obv) along areas that should be straight so you can line them all up. Once its perfect crop it back down to a clean image
