Oil Clay Breast Sculpting Guide

I need a clear, beginner-level tutorial that teaches how to sculpt realistic breasts in oil-based clay, with the main focus on understanding and blocking out the basic shapes and proportions.

Please walk me through the entire process—from conditioning the clay and setting up a simple armature, through roughing in the masses, locating key anatomical landmarks, and refining the overall form—so that a first-time sculptor can follow along confidently. While surface textures, finishing, and polishing are useful, they should stay secondary; the lesson really needs to concentrate on gesture, volume, symmetry, and proportion.

What I expect to receive:
• A step-by-step video (roughly 10–15 minutes) ​OR​ an illustrated PDF/photo-series with clear captions.(Video preferably)
• A short materials list covering the specific oil clay you recommend, basic sculpting tools, and any household substitutes a novice might already have.(I currently own monster clay-hard)
• Progress photos or screenshots at each major milestone so viewers can compare their work.
• Practical tips on keeping clay workable, fixing common proportional errors, and maintaining clean edges without premature detailing.

Keep the language simple, skip jargon whenever possible, and aim the pacing at complete beginners. If you have links to additional reference images or printable proportion guides, feel free to include them at the end as optional extras.
