Usually the features of a feminine face are considered to be:
-little or no brow bossing (no bone ridge above your eye sockets)
-small chin/jaw
-soft and rounded jawline
-small nose
-prominent cheeks
-an overall round facial structure (as opposed to square or elongated)
-thin and arched eyebrows (typically sitting higher on the face than male eyebrows)
-and a few other miscellaneous things like a short upper lip, proportionally larger eyes, etc.
By those standards, I think your face is definitely more on the feminine side of the spectrum.

I don't even see much of an Adam's apple. I think even pre-everything, your face would give you no trouble with passing.
