Tattoo on scars

I never thought that tattooing on scars would be so difficult, but it is. The lines don't look straight, even if you do them straight, also shaddows are fucked and so on. The story could be endless.
I am not sure if I have another tattoo today, or not. Well, whatever. I need to rest from tattoos and start working for my own sake.

That could've be an awesome tattoo. Also in reallity it looks way better.
