This is the perfect example of why you should never use a computer to translate an Arabic tattoo. I feel really sorry for you, because that is completely wrong. It doesn't even flow like Arabic writing does because you failed to have the letters connected.
Hey man. Sorry to tell you this but that is wrong. None of the letters are connected, and they are in reversed order. That happens when a computer that doesn't have Arabic tries to show Arabic fonts.
