I'm really stuck wth my story. Pease help!!!?

Are my characters too similar to other?

I'm writing a story and I need different types of characters personalities. There is an artsy one, a smart uptight, girly grl and a shy good girl. I'm afraid people will think it's too similar to Pretty Little Liars. I know it seems like it but these are the type of characters I want.

I’m writing a YA teen mystery/ drama novel. There are four man characters and I want to know what you think. They are all 16 year old girls, they are best friend and they can always depend on each other.

Character 1:

Brief overview of personality:

She is artsy and creative. She is kind of an introverted loner and only has a few close friends (The other three characters listed). He has one brother. Her family isn’t close. She loves to read and write. Although she can comes off as a little cold due to her shy nature she is sweet and compassionate and never wants to intentionally hurt anyone. Growing up her parents didn’t like how reclusive she was so they made her join clubs and sent her to camp. Even though she likes to believe in fairy tales once it comes to her own relationships she doesn’t do too well. She is realistic and knows when something is not worth the trouble. She has a sarcastic sense of humour.

Virtues:

She is forgiving, gentle, not judgemental and down to earth. Although she is shy she always stands up for what she believes in.

Vices:

Although she is shy she always stands up for what she believes in, likes to avoid drama, she is easily influenced and indecisive. She doesn’t always face her problems and prefers to ignore them.

Character 2:

Brief overview of personality:

She is a pretty girly girl. Although she is quiet popular, her best friends are the ones she’s had since childhood when she wasn’t so pretty and popular. Her parents divorced when she was a child so she barely sees her father, although it bothers her she pretends it doesn’t. She was very shy as a child but grew more confident after years of childhood therapy. She is kind of insecure but hides it well. She is witty, sarcastic and fun loving. Once she falls in love she is so happy but when things go bad she is devastated. Although she can be a little self-centred at times, in the end she would do anything for her friends and family. She is an only child. She has a fear of being abandoned and hates being lonely.

Virtues:

Her sense of humour, she stands up for her shyer friends, beneath the make-up she has a really good heart.

Vices:

She is a little pessimistic and unforgiving. She can be a little superficial and lies when it’s convenient for her.

Character 3:

Brief overview of personality:

She is an uptight perfectionist and a control freak. She hates letting other people take control and she’s really stuck in her own ways. It takes her a while to warm up to people, but once you’re her close friend she’d do almost anything for you. Her family isn’t close but they do get along. She gets very glum and down if something she does isn’t perfect. She likes to be as perfect as possible and hides all her flaws; this makes her come off as being a little fake and snobby. She is really smart and tries to impress her parents but they don’t really pay attention to her. She has two older college aged sibling.

Virtues:

She is dependable and is always there for her friends. Like character 2, she can be quiet pessimistic and unforgiving, but she accepts that people make mistake. She has a witty sense of humour. Like character 1, she is responsible and realistic,

Vices:

She holds silly grudges and can come off as being kind of cold. Can be really hard on herself is she fails and doesn’t always think things through. Her controlling attitude annoys her friends.

I don't know what to do, this is really frustrating me. No matter how much I try to change it, I can't stop comparing it to PLL.
