Horn
Curved: Curved horns should have one or more curves. The horns can curve forwards or backwards (or both). The curve can be as subtle as you want as long as it's visibly curved, meaning it shouldn't be a completely straight line. Curved horns should never curve so much that they coil around themselves.
Ridged: Ridged horns are more textured, scale-like or with small spikes. Ridged horns can be partially smooth or twirled, but must have some ridged texture present. If spines/spikes are present they must not be too tall and may not be confused for spined horns.
You're always welcome to draw your own horns, the examples below are intended as inspiration and to show some different ways ridged curved horns can look.
