@galadriel: Your tattoo looks great, but... I would like to warn you about the danger about this kind of henna.
The henna which they have used for your tattoo is forbidden in Belgium since beginning of July by the health-inspection. My friend puts henna's too, but she uses the natural one. Natural henna gives a dark brown result. Unnatural henna (chemicals have been added) give a black result. This looks nicer, but it's not good, because it can cause an allergy. And sometimes severe ones...
On the Gentse Feesten, henna's were forbidden. Even the natural ones.
Don't panic now <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> but please read the following articles:
article1 article 2 I hope I don't upset you now. There's only a little percentage of people who gets an allergy but just keep an eye on it.
