@JasperSandner I'm still not sure which hairstyle I should choose. But I sketched out my three thumbnail favs a bit. And I'm also not sure which one I should take xD argh!
Love the lineart sketches, I like the hairstyle on the one on the right the most! You can tell which thumbnail was your favorite, you've put the most rendering into it :P I'd say go with that one especially if you like it. Maybe do a couple more refined thumbs of that same pose/idea, adding in some torso twist, playing…
