I've seen two or three others too but yours seems most original. An I still think you should have it airbrushed and clearcoated into your Bowtie too. Your Dad does good work. I'm still trying to spell Christine with only 7 letters for my plates, that's what I'm going to call her.
Your avatar image is tight and I personally think you should seriously try to find some one who can do your bowties like your sig. I think the little cosmetic touches make the biggest difference and that one is deffinately on point.
