This is Marigold Heavenly Nostrils, one of the main protagonists of "Phoebe and Her Unicorn" by Dana Simpson, one of my favorite comic strips of all time. The comic is about a human girl named Phoebe Howell who is best friends with Marigold. However, even though the idea of a human being friends with a unicorn is strange, none of Phoebe's friends, teachers, or family members think having a unicorn friend is odd because the "shield of boringness" Marigold enacted makes living with a unicorn seem perfectly normal. Phoebe deals with classmates who shun her because she's different, but Phoebe likes being weird. In fact, she's blissfully happy being her "weird" self and doesn't want to be "normal." What I like about Phoebe as a character is that she's a positive role model for girls. She is a happy, confident misfit who loves being different from other kids, not caring if anyone thinks of her as weird. She's confused about not being liked by someone she wants to befriend, but is confident enough in herself not to get too sad. She speaks like an adult but with a child's perspective -- a tough line for a character to walk, and it works beautifully. Even though Marigold is usually quite vain and narcissistic, she is still a great friend to Phoebe and shares most of her personality traits.

The series is more than good; it's great. Phoebe is confident, smart, silly, and self-centered. Her unicorn, Marigold is also all of that -- and, like all unicorns, is also mesmerized by her own beauty. This series tackles issues of fitting in, popularity, loneliness, friendship, honesty and what it means to be yourself. It's very similar to Calvin and Hobbes, but without quite as much adult appeal. But despite that, Phoebe and Her Unicorn is a great comic that both kids and adults can enjoy, and I highly recommend checking it out on GoComics if you're interested in reading it yourself. 

Hope you like my drawing of Marigold!
