Within context, this image (which is framed to look like a photo taken with a smartphone) is set sometime after Detective Ken has had a few big cases to his name, only to be recognised on a late summer evening by someone who has been following his work. Why doesn't it contain the photographer/fan? Because who only takes 1 photo of someone they admire? As for the cat - either it walked into frame, or the cat is with him. Even the fan wouldn't be sure about this unless he or she asked.
As far as the creative process is concerned, I'm becoming more comfortable with the incorporation of certain styles that I want to emulate, as well as certain approaches on Photoshop itself.
Once again, feel free to provide constructive critique, because I'll need it.
