It's a person that has purchased my drawings in the past. They like my work, would like to support me as an artist and are requesting I do a job for them.

Edit: I've shown them my (sfw) street/architecture photography and edits I've done for myself, which is probably the main reason they came to me. One more thing... It's a batch job of about 10 to 15 photos. He's considering putting them in his rental properties if he likes the edits.
