[So, I'm opting for a written description because I just can't find a pic I'm satisfied with ^.^ And I hope it's okay that the Bio and Personality aren't too detailed, I like to have room for them to develop during the RP.
Feel free to tell me if something doesn't fit or sound right ;)]

[hider=Lauren Maroney]Name: Lauren Maria Maroney
Age/Year: 18/ seventh year
Gender: Female
Appearance: Lauren is about 5'6", slender in build and has light olive skin, showing her father's italian heritage mixed with her mother's purely british one. She has long, dark brown hair that falls in waves over her shoulders and halfway down her back. She is kind of pretty but would only be average if not for the exotic look of her features working in her favour there, especially because of her big, light brown eyes and long dark eye-lashes. Matching her personality, she has a mature look to her and is usually in control of her facial expressions.
Blood purity: Muggle-born
House: Hufflepuff
Short Bio: Lauren was born and raised in a muggle household. Neither her parents, nor her three younger siblings were or turned out to be wizards, so of course it was hard for her to adapt to Hogwarts at first. However, due to her personality it didn't take her long to find friends who explained this new world to her and told her everything she needed to know. It took her years to get used to changing back and forth between those two so very different worlds and she pretty much constantly misses one of them, even now. 
Lauren has been a serious student from the start, who works hard for her good grades. The only thing she easily excells at his Herbology, most likely, because it had been her favourite from the very first time she stepped a foot into the greenhouses and she's just really interested in it. Now, in her last year, she looks back at her years with a lot of fond memories, and has yet to get into any real trouble, though with everything that has been happening in the school, she fears that will change this year. She is studying hard to master the N.E.W.T.'s coming up, because she is aspiring to become a healer.
Likes: Herbology, Experiments, Coffee 
Dislikes: Surprises, Intolerance, Moving Stairways
Personality: Lauren appears to be mature cause she is quiet and to keep calm in stressful situations and prefers to think before she acts. She is very patient and caring, probably due to looking after her three younger siblings whenever she is at home. She dislikes confrontations, but that doesn't mean she is shy or weak, she just can't stand people being unreasonable and hot-headed. Lauren is very fond of her friends and in return well-liked, and though not quick to judge, she is not quick to truly trust someone either. You wouldn't expect it, but she has quite the dark sense of humour and can be rather sarcastic and pessimistic if she's in a bad mood.
Wand wood: Chestnut
Wand Core: (tbd by GM Wand Cores)
Patronus Form: Otter
Interesting Facts: - She is kind of directionally challenged and therefore constantly getting confused by the moving stairways. It had gotten a lot better, but it still happens to her to be late to class because she got a little lost along the way. She prefers walking there with at least one other person, preferably more.
- She has been singing in the school's choir since her third year.
- The only one calling her by her second name is her father, other than her family barely anyone knows she even has one.
- When she was young she wanted to become a doctor, like her father.[/hider]

[I might make a few changes later, should be minor ones, but I'll make sure to point them out if I do]
