This is a character concept named Elise. She is a self proclaimed tinkerer in a post apocalyptic land of fantasy where mankind overstepped their boundaries in machine warfare. She can be a bit hot tempered but is pretty kind and light hearted once you get beyond that thinly coated candy shell exterior.
Entirely drawn with the pen in ConceptsApp with the Copic marker shading. I tried to do only show myself 2 or 3 adjustments to get used to the tool but also simulate only drawing with an ink pen and no eraser.
