Well, thats the fun of it.. being as how you didn't exactly conceive of the idea of two bows, Ive seen it on everything from collar bones to hips to one on either arm, no one can really steal this design from you. The placing is cool, but you aren't the first person to put tattoos on fingers/knuckles either. Either way, well executed.
The idea of placing bows on thumbs was quite original. Haven't seen that before, although Im sure its been done. I don't understand what you where getting at with your comment nor its reason. Either way, well executed.
