How to Correct Skull and Head Proportions in Anatomical Drawing for 17-Year-Old Students

Let's address each part of the corrections step by step to fix the anatomical drawing issues:

1. Resizing the Head and Skull:
   First, revert the head's size back to its original proportions before the skull was enlarged. The skull should be resized to fit the smaller head naturally. Remember, the skull supports and defines the shape of the head beneath, so their sizes must correspond accurately to maintain anatomical correctness.
2. Removing the Orbicularis Oculi Muscle:
   The orbicularis oculi is the circular muscle around the eye that helps in eyelid movement. If it’s visually cluttering your sketch or you need to highlight the bone structure, carefully erase or omit this muscle layer from your drawing. This will make the eye socket and surrounding bones clearer.
3. Closing the Jaws:
   To show closed jaws, align the lower jaw (mandible) with the upper jaw so there's no gap. Inside the mouth, fill the area with a solid black color to avoid showing details like the tongue, which simplifies the drawing and focuses on bone structure.
   Also, correct the angle of the lower jaw: instead of a sharp, right angle, the mandible's angle should be more blunt and gently curved at the jawline. This reflects natural human anatomy more accurately.
4. Drawing the Cheekbone (Zygomatic Bone):
   The cheekbone defines much of the face’s contour. Sketch it following the reference, paying close attention to the shape and angle. The zygomatic arch should appear smooth but prominent. Connect the cheekbone line to adjacent bones correctly, ensuring your skull shape matches the reference as closely as possible.

Tip: Always use a reference image side-by-side while adjusting your drawing for the most accuracy. You can overlay your sketch on the reference or measure distances and angles to maintain proportionality.
