The bottom portion of your face is indeed "very" masculine. With your hand hide your nose/mouth on a picture onscreen, you see a girl. Now hide the upper portion of your face, unmistakably male.
Your nose is ok I think it's pretty much the mouth/jaw. Without a side/45 angle pic I can't tell if your brow ridge is in male territory though.
One word of advice I can give you: Don't smile like that it's just not flattering... Teethy smiles are just not for most MTFs it highlights your complete lack of upper lip. Shy smiles, smirks work best because as MAAB our face is more designed to frown, look angry and make freakin hideous warmongering faces distorted by hatred.
I look 100% bio and I wouldn't smile like that.
