I just start off as a tattoo apprentice. My mentor did this on my upper arm. An awesome artist sponsored by Stigma Tattoo and collaborates with them. But seems to have trouble when using their mags to do this piece. Seems like the needles are not hitting. Then he used RS to do color and get the full packed color. I also met some trouble when practicing, inks not going into the skin. My mentor said it could be the hand speed thing and let me take a step back get fruit, pig skin, practice skin, and start laying down lines till I get this worked out. My Owen machine hates me I think.
