I think you look fab! The only advice I can give is constantly observe girls and women. Much can be learned from them.
In terms of passing - For a long time I was obsessed with passing as a woman when crossdressing. While that still matters, I've noticed that it has become more important for me to pass with dignity. Put another way, I know I look like a man in a frock when in public. But I want to look very good as a man in a frock in public 😀
