Just a quick sample. With most of my panels I’ll use a wide format to enhance the cinematic feel and Ill also introduce a short depth of field. This is achieved in Photoshop  by duplicating the art layer, applying a 2.1 Gaussian Blur to the duplicated layer and then activating a layer mask for that layer. With a layer mask available you can choose which parts of the blurred image will remain while erased areas will expose the clean art beneath.
