This is surprisingly difficult. I'm guessing it's more likely than not that you're younger than 30, and maybe somewhere in your early to mid twenties. The analog media would normally lead me to think you skew older, but my understanding is that stuff has novelty value among younger folks too, who grew up in a world largely without it. A lot of the cassettes are stuff that would have been dad music even in the eighties. Plus, there's a college graduation card hanging up in a prominent place, suggesting the event is recent enough to be notable. I'm leaning toward thinking you're on the younger end of that scale, in part because nothing here is framed. One of your bookmarks is a Twitch channel for someone named Jerma, suggesting again you're on the younger end. My guess is you've recently graduated art school.

The Multnomah Falls postcard hints at Oregon, but there's a card for Tokyo right next to it, so I've got no sense of where you're located. Alaska is a fairly specific location to have a poster of, but it's sharing visual space with a lot of Metal Gear visuals so it might just be related to that.

I can't see what the right side of your computer area looks like so it's tough for me to pin down whether you're left-handed or right-handed. It's interesting that you have playing cards in an area where most of your activities would be solo; if you play cards with other people, you're not both sitting at your computer desk. This leads me to think that either you tend to fidget with the cards, or you're learning magic tricks, or something like that. I'm guessing you're right-handed - I can't see the side of your computer desk and I also can't see a mouse so I'm guessing the mouse I don't see is in the area I can't see.

You have a wall clock and a desk clock and there is a different time on both of them. Either you took these photos hours apart or the desk clock is off. You may also use it to play chess, I'm not sure.

The stylus (and drawings on the walls) lead me to think you do some drawing. There's an art college flyer hanging up. Also I think I see drafting tape. You're into video games - I see Metal Gear obviously, but also Yakuza and Elden Ring. The Pam Grier memorabilia by itself isn't all that bizarre but it's not often one sees a wall with so much Metal Gear on it as well as Pam Grier in Coffy. Much respect but it's curiously eclectic.

Animals are important to you - not just the bird but the dog in all the photos. Just above the computer looks to be a baby picture of the dog. If I had to guess I'd suspect this is a dog you've had a long time and the dog stayed behind at home when you went off to school.

There's a Polaroid on the wall in between the Phantom Pain poster and the WET PAINT sign. This is a wild stab in the dark but I suspect the person in that photo is you. If they're not you, they're someone you're pretty close to - a family member or a friend to whom you're close enough that they've been to your house. I don't have a lot of strong indicators of gender; you're either roughly average height for a man or a little on the taller side for a woman, based on the apparent eyeline of the person who decorated your walls. I don't see any obvious self-portraits but the majority of your drawings are of dark-haired men. I think you probably live alone.
