@JadeAriane about half right. Brunette (although on the darker side), yes; but I’m Asian (Indian). I wear glasses sometimes, but I prefer contacts. Around 5’5" with an interest in… er… everything. Liberal arts included.
Hard to find someone who hasn’t been done 
Outgoing musical/band type who loves to challenge himself
Uhm, @NWIStudent, are you a 5’10" white guy who loves… basketball? And… has a dog?
Man, how do you guys even come up with guesses? Haha
Let’s see, @marshmallowpop. Are you a shy teenage girl, around 5’ 4"? Sort of pale, with T shirts that have really bad puns on them. Dark brown hair in a ponytail? Idk, making a random guess lol.
I could see @marshmallowpop having really good eyes. Like a light blue.
@marshmallowpop I am a 5’10" white guy! No dog though, and I like (but do not love) basketball.
As for sightreader, just a guess, would be an average-height male who is in debate/speech and loves to read.
@Sightreader You’re a 6"0’ white male, black short hair, and 16. You like to play tennis? No idea.
@Kawaiiii 5’4’ Asian girl, black hair, loves anime, and 16? Lol
@Sightreader Haha, wow, kind of the opposite. I’m really outgoing and talkative, not shy at all. I have a few punny t-shirts, but not many (hm, I might need to change that, though…)
Uhm, my hair’s nearly black, and my eyes are too (though having blue eyes would be really cool). Paleness wise - I’m from the Asian subcontinent, but I’m of Afghan descent, so I’m pretty white. Huh, do marshmallows really say “shy, pale, and punny girl?”
@NWIStudent yesssssssssss, I feel so accomplished right now 
too bad you don’t have a dog, haha.
I was going to guess that you liked hockey at first, but then I figured that more people watch basketball
