Just to prepare you the color is going to be the worst part. Just dont drink or smoke ganja before hand. Drinking will make you bleed more and the ganja will make you feel the pain more.
It's funny that you say this because the artist said the color isn't as bad as the outline. He said the outline is worse because you're putting the ink down much darker than you do with the color. He said the outline is thicker which is why it is worse. Either way it's not that bad. Can't wait to get this thing completed though.
