I like those ideas. Being an animal lover, some sort of animal would of course be my ideal choice. I was actually browsing for inspiration earlier when I spotted an awesome tattoo of a raven, so maybe something like a crow/raven could be a possibility =)

Old school roses was actually one of my first thoughts, it’s not really the most imaginative idea but then my imagination sucks anyway! Another idea was vines but I always imagine them looking too messy.
