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.
Smooth: Smooth horns will always be completely smooth, with no extra points, ridges or textures.
You're always welcome to draw your own horns, the examples below are intended as inspiration and to show some different ways smooth curved horns can look.
