They dont do that in the show...?

ambris:

Take a look at even this bit from the gif I post earlier.

It absolutely curves in at the bottom.

It’s only shown on one side here, and because they use colored tones for outlines instead of black (like I do), so it’s a hell of a lot more subtle. And does actually look better too, now that I’m really studying it. I may take reevaluate how I draw horns based on that.

But you know, yes, they do that in the show too.

It’s not really a curve on the horn itself, though. It’s more of indicator of the horn being round at the base (the base being where the horn meets the head).

In early episodes, it was a complete line.
