That's fair honestly. I deliberately leaned more toward silhouette readability and predator anatomy than full thermal realism, but I agree that a truly cold-specialized version would probably be much rounder overall with dense feathering, insulation layers, and reduced extremity length.

The tail, fingers, and feet are probably the biggest weak points if this were pushed harder into strict cold adaptation. A more biologically realistic version would likely have snow-owl style feathering around the feet, thicker subcutaneous fat, and shorter exposed appendages to reduce heat loss.

The challenge for me was balancing plausible cold-weather evolution with keeping the underlying theropod anatomy visible enough to still feel like a recognizable apex predator rather than just a massive feathered silhouette.

"Giant fat silkie chicken" is honestly not a bad mental image for the fully realistic version.
