Use dark reds, maroons, browns, and blacks for blood and tissue
Sketch the overall shape first with rough forms
Add irregular edges to make the damage look torn
Vary line thickness to create depth and texture
Layer darker tones underneath and brighter reds on top
Draw splatter in different sizes and directions
Include drips, streaks, and pooled areas for realism
Add shadows around the gore to make it stand out
Use highlights sparingly to suggest wet surfaces
Keep shapes uneven and asymmetrical
Add small fragments, strands, or clumps for detail
Blend colors where blood would be wet and fresh
Smudge edges where material would be smeared
Contrast gore with cleaner surrounding areas
Use references for anatomy and texture accuracy
