If you liked the camera's effects you would probably benefit from learning makeup as well, since it can make your skin look smoother. There's other nice things it can do too of course but that's one that can often help with looking more feminine. I believe there's also makeup techniques to hide beard shadows? Idk for sure though I have no experience.

Also yeah definitely grow out your hair first if you want long hair, it can do incredible work for how well you pass. It won't get you all of the way but it will get you more than you'd expect, especially when you style it femininely.
