In order to get the product from above. I first saved the mirror and then I cropped a small part of the fire picture to the size that fits the mirror with the magnetic lasso tool. Then using the erasers to clean out the parts that I don't want. Next I changed the opacity of the fire so that it's not too bright that might cover the third picture. Finally, I used the magnetic lasso tool to crop out the monster picture, the placed it in the middle of the page, and turned down the opacity, and used the less hardness eraser to erase the surrounding so that it creates a blurry effect and help pictures join better.
EXTRA: I went under the filter page and opened Unsharp mask to clarify and sharpen the image. Afterwards, I went under the Lens Correction, under custom edit the Geometric Distortion to remove Distortion.
