I, personally, would've offset the back spikes (not sure what else to call the protrusions that the ghosts have) a little to help with giving it a little more depth. Since the are lined up, the lines meet up (especially on the front spike, you can the bottom line go straight back). Other than that, it looks cool. In the end, it's your body and you are free to do what you want. I love tattoos and have a few myself. My favourites are the ones my wife got me for Fathers day. I have the Zeon and E.F.S.F symbols from the original gundam series on my legs.
