I have small hands and short fingers so I always worry that stacking pushes my ering to the point where it looks odd. How far do you stack your rings before you hit your knuckle? It's hard for me to judge on my finger. Would love to see how high you stack yours.
I think it looks fine but the real question is how comfortable it is. Can you bend your finger without it feeling tight? I too have short fingers and don't stack more than my engagement ring and wedding band because it is simply not comfortable for me.
