But small tattoos don't look as good as large tattoos. You can't get much intricate detail and/or colour in a two inch square.
If you're coming from a position of not really liking tattoos, then I can see why they look large and why you think people will regret them. But people who like and want tattoos generally want them to be large and detailed.
Vicky obviously likes tattoos, wanted more tattoos prior to the accident, and now has a "you only live once" attitude. Good on her. I didn't find the elephants that aesthetically pleasing, personally, but for her it was really meaningful so whether I like it or not is irrelevant
