Very close. I'm watching with a high index-of-suspicion, as if someone told me you're trans and I'm trying to decide if they're pulling my leg or not.
Result: I might suspect after a while. I probably would believe an outing. This is an acid-test though, so I'd give it a high passing grade, at least a B. Go out with friends and be yourself, I think, because you're not going to get better without more confidence.
Weakest point is your voice, but then I'm
really intensely critical there. For example, at "probably worrying about
nothing" you hit a D2. That's not impossibly low for a contralto, but it's way down there and she'd probably recover by bouncing back up to A2 or higher, and that's about as high as you go. "I just want to
do another one" is around B or Bb2.
Your resonance is good, though, and so is the way you voice gets gravelly near the bottom. I suspect you have many of the right instincts, but you have difficulty accessing the higher pitches. This is a technique thing; when you do it right, you can hit C5, yes 5, without much difficulty - and that's way above normal speaking pitches. "Male vocalist mixed voice" should get you some good resources, but you'll have to practice in guy voice.
So, what does this mean?
Rain, page 11 and 12, and the author's comment on 11. I think you have cues enough to be reliably gendered female, especially in a group.
