This is Mangle - but her furry AU version. Her name is Megan in the AU.

During her young years, she had long hair. When she became a teen (around 15), when she became stressed, she started cutting her hair. One day, when she had a meltdown, she cut her hair short; to the point it is shoulder length.

This isn't her as a teen, but, as an adult with long hair, since, at one point, she let her hair grow whilst taking a vacation for a few months. Once she came back home, her friends were surprised to notice her hair being long. After a week of staying home, she finally cut her hair back to shoulder length.

Also yes, this is practice. I was just practicing painting- especially painting hair.. since, I'm not generally the best when it comes to shading the hair.
