<p>Kids would be pretty confused if Aang's eyes looked completely different on the poster.
</p><p>Also,

Sun Wukong (except...human. And not okay with killing.)

Gyatso did have narrower eyes.
<p>Almost all the kids in the show have larger eyes, while many of the adults have smaller eyes.
</p><p>This is because traditionally in artwork and animation, children are portrayed as having larger eyes compared to adults.
</p><p>Large eyes are associated with innocence.
</p><p>Narrower eyes are assoiciated with being older (think old people with squinty eyes), or being less innocent.

</p><p>Also, Azula and Ty Lee are about the same age, but Ty Lee is innocent and friendly, and thus has larger eyes than Azula, who is manipulative and..many times...cruel.
