I had to pop out of seclusion for this topic! I know you've seen pictures of mine, but here they are again. I also have a scorpion on my right hip that I don't have a photo of. The next one I'm planning on getting is an Orion to sit opposite the scorpion, but I haven't decided how I want it yet, or whether it should go back or hip, etc. The one on my hip did not hurt at all. The process felt sort of itchy, actually. I ripped the scab off on a pair of jeans though, so it's in major need of a retouch.
The ones on my feet hurt. A lot. Ask my roommate, who held my hand.
But they were really quick (less than five minutes each) because they're just black lines. I have a thing for plain black tattoos.
The picture was taken the day I got the "I think" done (which was about 5 months after I got the "I am" done), which is why it's all red and shiny. I took the picture in a mirror and reversed it, in case you were wondering if I had it done backwards.
