Look forward to this. Head construction is something I've been hoping to get better at; ideally this means moving away from being at the mercy of reference images while at the same time not simplifying too much from lack of understanding and being stuck at a limited range of angles.

For S-curves I decided to have a bit of fun and play with river-like landscapes. The contrast setting wasn't really cooperating but you aren't actually missing anything. The last page (the one where you have 8 boxes) I was fatigued just trying to "wing it" admittedly and paid the penalty for not taking the time to do ghosting. Ballpoint pen is more forgiving than any other pen and that wasn't going to save a reckless lead weighted wrist then!
