Sketch for @lord_gris challenge! (Patreon)

How rough are your sketches? Here you have an example of how usually my sketches look! ^^

I want to participate in this challenge. The character by the artist has a beautiful water hair and I needed to explore this concept and create a story with it. 

In addition, with this drawing I'll try a (more or less) monochromatic color scheme! I'll be uploading next steps!
