Neveen is one of my most recent, but also most well- rounded OC's. I have already used her in a few non-cannon short stories and stuff like that, and though she jumps from one universe to another to fit my needs there's a good deal of consistancy in her story. I won't go into too much detail yet, but I've made good use of a certain picrew.
Above, left, is Neveen age ~13. She has short hair, and its tight curls make a fluffy halo around her head. Her eyes are brown. She is not happy. She is enduring a toxic situation. She wears baggy clothing in dark or neutral colors, and does not have a reasonable understanding of how to express her desires and boundaries.
On the right, Neveen has reached somewhere around 20, though in some settings she will reach this point much earlier. She has figured out how to enjoy little things. She has friends, but doesn't quite know what to do with them. Her hair is longer, and she often pulls part of it forward to veil her face. She wears baggy clothing still, but explores somewhat brighter colors and likes wearing layers. She gets her ears peirced during this stage, and starts defining her boundaries - though she still struggles to express them. She will spend many years playing with different styles and presentations, exploring her self, her gender, and her faith. Some things she figures out well before others.
And this is my most recent, and oldest, version of Neveen. She is about 28 years old, or more. She is confident in who she is. She has found her calling. Her hair is much longer, braided and held back by white ribbons. She wears earth tones, warm colors, and deep greens. She has a new family, a chosen family who love and support her. She likes swimming in rivers at night, and is fiercely protective of her loved ones. She takes care to speak kindly to those who would do kindness in turn, but should anyone show unbased hatred she will definitely throw hands. She finds grave yards peaceful places. Death is not the end of a story, in her mind, it is a step in a ceaseless cycle in which we all participate. She gets tattoos when they call to her, most recent of which is the form of an egyptian white vulture in flight, its wings stretching across her back, just under her shoulder blades. She is happy.
