If anyone ever asks you for tattoo advice: "get enough sleep" needs to be at the top of the list. I've barely slept but a couple hours each of the last three nights.... and I could barely make it through the final 4 hours of tattooing needed to complete my sleeve. After about an hour, everything just hurt bad, and I had very little tolerance for pain this time around.
Here's a pic of the final sleeve. Some of the oranges are really yellow but inflamed... and there is actually no red in the swirling spiral on the back of the arm -- just red from the work.
Going back in a month for some touch-up work (not a lot of green held in the dragon's head first time around) and I will post healed photos in a few weeks.
