Derpy Hooves ninja

So one day I was watching some images in the Internet and I saw Derpy Hooves as a ninja and I decided to make one myself. I´m not sure if I should change the title to "Derpy Hooves kunoichi" since Derpy is female.

Edit

Thanks to equestria daily for accepting this picture, and thanks for all the comments that you have made, I have read them all and I hope that you can leave more feedback, I want to improve, I´m not going to change the title (its easier to find this way).
