INTERESTS?

Right now I have photo praxis at my school in which we learn about taking photos -  diaphragm, focus and etc. also one of the tasks is show in the photo your interests, but I can't take a photo of it!
How can I show kpop? Drawing? or photographing?
I can't just take a photo of my pc with bigbang photo on it or take a photo of my pencil case...
So I'm having this loss of ideas and I'm kinda stressed about this.
also I made these doodles wich kinda is similar with the theme in photo praxis - people with interests or in my case mans face and something around which is interesting to him, islands, water, electricity, diamonds...
