Dragon tattoos used to be mostly a male dominated design. You didn't see very many women with them. Now more women are choosing this design from small ones to full on body tattoos.
Adding the cherry blossoms helps to make this a more feminine looking tattoo.
As you can see by these tattoos that depending on the style of your design and the addition of little details such as color choice, addition of flowers or other feminine details you can have a dragon tattoo that isn't masculine looking.
