My main focus is making sure the teeth look natural and don't stand out unnaturally.

I've paid special attention to the tiny bumps on the tongue (taste buds), the shape of the back teeth, and subtle color variations throughout the mouth.

I could push the details further for even more realism, but like the rest of the figure, I've intentionally kept things a little more balanced.

My goal is to make the mouth look natural at any distance, from full-body shots to extreme close-ups, rather than optimizing it for just one lighting setup or camera angle.

Even when her mouth is wide open, I want the teeth, tongue, and inner mouth to look natural under different lighting conditions.

Just like the skin, eyes, and eyelashes, I've designed the mouth to be easy to render without needing special adjustments.

I want artists to be able to use a wide range of expressions without having to worry about how the inside of the mouth will look.
