Yes! Feminine traits!To start with, more eyelashes? I don't see any to use the word "more", no offense.Some could have maybe bigger hips, mainly Rarity cause of her lady personality, Applejack from her hard work by kicking the trees, and Rainbow Dash cause she's the sportive one.The feet need to be more slim.To be honest, the one who looks good is Rainbow Dash, Twilight is OK, while Rarity, Applejack and Sunset Shimmer, they look masculine ONLY in the faces.Also...In this work of yours...Even if I don't see any eyelashes, the key was the head form and slim neck.My best suggestion is, since you have an anime/manga style, look maybe at some mangas and animes.Don't ask me which, cause I don't read many.
