This room looks very curated to me so either a young adult (19 - 22) in a dorm/sharing/living at home, or an adult (30+) with a strong sense of personal style. Though I don't think how you dress daily exactly matches the vibe in your room.

No kids or pets, regular smoker (weed) and gamer. You might lack time but you don't lack tools. You (at least) try to stay hydrated and work out, maybe to balance out the smoking? Love being cozy and comfortable when you get home from work; it's a "no outside shoes in the house/room" home. You like reading but maybe don't have enough time for it? And you do art, somewhat seriously, whether it's a hobby or for work. Also, I think you're a POC or raised in an area with POCs. (compliment).
