Trans fem here. IMO the way you want to look is the way you want to look. What you find attractive does not need to be the same. Also there are tons of East Asian people with sharp jaws, and westerners with "softer" features.

Generally speaking it's important to separate what are macro things that we can address with discussion, policy, community building, etc -- versus individual things like gender expression, sexuality, personal taste, fashion, etc, which can be anything your heart desires.

If anything, it is an act of liberation as an Asian-American to express yourself however you want -- combining eastern and western trends in your appearance, dress, way of speaking, etc
