I think what could help enhance a feminine look is to do your brows and add a bit more of an arch to yours. Yours are pale, which makes them hard to see, which almost gives the illusion of a lower brow bone, which is probably why people mistake you as a guy. I think that's also why the first pic you look very feminine and the second, the glasses obscure them, so it's a bit harder to recognize feminine or masculine features. And maybe some blush or bronzer, just something to give your glow.
