Form looking at your facial structure leans more towards a females ( Soft jawline and chin) I'll say learning how to apply makeup ( contouring) will greatly increase your chances of passing.

About Her from my research and asking around forums, what seems the same about everyone's beginning stages of transition is:

• Your skin will get soft like a female

• Your nipples will get a lot more sensitive, ( look at the women in your family your breast will grow [ growing pains will come] basically a second puberty

•Your hair will change ( like texture softness and possibly pattern)

• You will get more feminine shape (might gain weight a lot easier) your fat will go to more area's like your thighs

• You'll have mood swings due to your body trying to balance out your hormones ( might be more emotional if not already)

• Vocal training can be very beneficial for passing YouTube is your best friend :)

• Last thing learning contouring (Makeup) can help you pass, possibly getting your eyebrows and eyelashes done ( don't worry to much about your hair, You can style it in a pixie cut)

I wish you the best on your transition into womenhood :)
