Creating art effects in Photoshop

How are you guys! I've been dipping my toes into making album art recently, and I've had a lot of fun, exploring designs people have been putting together. In particular, I've always been fascinated by the art style that is created, such as this image I have uploaded. I'm just curious how some of the experts on here might tackle creating a similar affect on the people in the image. Looking forward to hearing your responses!
