Pose: San Judas Tadeo is typically depicted standing in a serene and noble pose. He often holds an image of Jesus Christ in his right hand, symbolizing his role as a faithful apostle. The left hand might be raised in a gesture of blessing or holding a scroll, representing his writings and teachings.

Clothing:

Tunic: A traditional long, flowing tunic in rich colors, such as deep green or purple, is commonly seen. The tunic should have fine folds and intricate fabric detailing to showcase movement and realism.

Cloak: A mantle or cloak drapes over his shoulders, typically in a contrasting color, like white or gold. The fabric should be textured to show depth and weight, as though it’s naturally draped.

Facial Expression: San Judas Tadeo is often portrayed with a compassionate and calm expression, embodying his role as a patron saint of desperate causes. His eyes may be looking forward or slightly down, conveying both wisdom and understanding. A slight, gentle smile or a soft, serene expression could add to the peace he exudes.

Features:

Hair: San Judas is usually depicted with dark, wavy hair and a beard, which should have a natural flow and softness in the modeling.

Eyes: Deep, soulful eyes that reflect a sense of peace and faith.

Aura: A halo or divine light might surround his head, which could be glowing or radiating subtly in the 3D model for added sanctity.

Accessories:

Medallion/Emblem: Some depictions include a medallion or a sign of a flame or a staff.

Iconography: In some versions, the image of Jesus or a flame might be more prominently featured in the model.

Texture and Material: The model should have detailed textures for the fabric of his clothes, skin, hair, and the background. His cloak might have a fine velvet or satin look with a glossy sheen, while the skin should have realistic shading and slight imperfections. A stone or wood texture for the background, or possibly an altar-like setting, can add depth.

Lighting: Soft, divine light can highlight San Judas’ figure, with shadows providing contrast to emphasize the folds of the clothes and facial details. The lighting should evoke a sense of holiness.
