{I'm going to be doing a combination of teaching and posting. Everything below the line is my next post, everything above the line is my "teaching" and suggestions}
What Jovi has done here is a perfectly good RP post. It's three lines, descriptive, and shows some sort of action. She walked into the cafeteria, got a burger, and looked around. It's usually "polite" to the author of an RP to write a minimum of three, descriptive lines. Try to emulate this.
She wrote in the third person. Also important...
In my post, I'm going to try to be an "almost over-descriptive" writer (like I normally am... sorry). As a side note, I use italics to denote either emphasis (a common literary technique) and internal thoughts. Try to determine which is which.
Otebon dry rubbed his hands dry after leaving the bathroom. Being in his senior year, teaching students was a bit of a requirement. Luckily, he was able to get a job in the Chemistry Department, so it was more fun than tedious.
Otebon loved chemicals.
Without much looking around, he went straight to the cafeteria line. It was burger day, so he got himself a double with bacon and went for the fries and sodas. Grabbing a Pepsi from the fridge and heading to the pay counters, he swiped his Student ID and paid for his meal with his Meal Points.
Otebon smiled when he did this. His friends back in the door routinely referred to the Meal Points as "Monopoly Money". It didn't exist and it didn't matter.
Coming out of the cafeteria, he went to go sit in his favorite spot without really paying much attention to what was going on around him. His chair was next to the window, giving him a great view of the soccer field outside, and he plopped his backpack down in the seat beside him.
First things first, Otebon thought to himself as he laid back and let the sun warm his dark grey and white fur. Some of the tougher species in here may make fun of him for it, but this Timber Wolf loved to bask in the sun.
