I've been learning how to use the "Live Mesh Warp Filter" in Affinity Photo 2. I created mesh warp filters on top of the blank pages. Then I dropped 2 fantasy art pages onto the filtered spots and they instantly warped into the book pages. I resized the righthand image after adding it and moved it around - the live updating works brilliantly.
