Animal Skull Study
3 Weeks | 100 pts
Additive Sculpting - Process Refinement
Project Brief:
In this project, you will design and sculpt a creature skull using the provided custom brush. The creature may be real, extinct, or entirely conceptual, but it must feel anatomically believable and grounded in biological logic.
Your final sculpture must be presented as if it were a physical artifact on display in a natural history museum. The emphasis is on structure, material believability, craftsmanship, and professional presentation.
This is not a character or creature bust. This is a skeletal study.
Design Constraints & Allowances
Alphas and surface noise should not replace sculpted form. To maintain focus while encouraging realism:
One skull & one base only (Base may be tabletop or wall mounted display)
No soft tissue, skin, fur, or eyes
No foreign objects (Nails, Rods, Weapons, Floral, etc)
No exaggerated fantasy elements unless structurally justified
Forms must interlock and feel mechanically plausible
Asymmetry & Natural Variation
To avoid overly perfect or mirrored results, students may and are encouraged to introduce:
Pathologies (healed fractures, deformities, abnormal growth)
Damage (chips, cracks, missing sections)
Weathering or erosion
Subtle color variation or staining
Slight structural asymmetry
Any asymmetry should feel biological or environmental, not decorative.
These choices should reinforce the idea that this skull belonged to a once-living organism.

AI RENFERENCE
You are welcome to use AI in my class as long as you site your use of it. Do not pass along AI work of any type as your own. Doing so will make you subject to potential academic penalties.
TRADITIONAL REFERENCE
Gathering from Google is good. Going outside and capturing your own reference is ideal. A great local source is the Natural History Museum in L.A.
For any ZBrush iPad users, you have the advantage of working with photogrammetry now - the ability to scan real world objects.
See me for further details on this.
ZBRUSH ARTIST WORK
There is tremendous value in the study of other artist’s work. It helps to aspire to a higher level of work quicker when comparing your output to a finished goal. I’m often inspired by the success of others.

Rorschach Tests
Hermann Rorschach was a Swiss psychiatrist best known for developing the Rorschach inkblot test in the early 20th century. He was interested in how people perceive and interpret ambiguous visual information, believing those interpretations could reveal patterns in personality and thinking.
The Rorschach test involves showing subjects a series of symmetrical inkblots and asking what they see. Rather than focusing on right or wrong answers, Rorschach studied how people described the images, including form, movement, emotion, and detail. His work became influential in psychology, art, and design, especially in understanding projection, imagination, and visual interpretation.
