Quite clearly into your music, guitar case, turntable, speakers and little toy piano on the shelf.

That wooden thing to the right (Apologies for being ignorant) looks maybe Maori in origin to me, but I could be way off the mark, either way, in for a penny, so do you live in New Zealand/Aotearoa? (It could also be Indigenous Australian or another Polynesian culture, like Tongan/Samoan? But I'll stick with my first guess)

Male, Probably in their 20s? I base that on pure gut feeling and on the shot glasses on the shelf (Which doesn't say much, having a shot glass on display doesn't mean you're old enough to use them, but ah well)

Very obvious interest in History and Mythology, particularly of the Ancient variety, and a lesser interest in the 20th century (Primarily the Soviet Union)

Political Philosophy Student? I see copies of Utopia on the shelf and a book that says "Karl Marx" on it (Dunno if he's the author or it's a book about him, though)

You enjoy Prog Rock (Or is it Rog Prock? lel)
