We need a layout that shows two objects on a single photograph:
On the top half of the layout we need photograph 1a turned into a sketch (keep the handwritten texts, remove the person in the photo, make background plain white, and turn photo of bag into a hand-drawn sketch).
On the bottom half of the layout we need photograph 1b on the same white background.
So at the end these two photos will be shown in one single image, but the top looking like a sketch and the bottom looking like a photo of the final product.
Please do the same for all other photos (2a and 2b, 3a and 3b, 4a and 4b).
