I like the concept. I was thinking of an armband with the saying. Good thing I've not gotten one yet, I thought 'Bragh' was spelled as 'Braugh'
The shamrock is wonderful, I can tell the celtic knotwork was done well. That's another reason why I've not gotten a tat yet. I've seen some people whose tats were done by people who didn't know how to do celtic knotwork, so it looked more tribal than celtic.
The shading of the colors is also fantastic. I love how the green varies. IS there some white on the outside at places? It looks like it in this pic. That and the bold black lines helps makes the shamrock stand out and look 3-D
