Instead of looking for something someone else did, you might want to consider actually going to the shop you want to use and speak to the artist. Make an appt ad offer to pay him/her for their time and start throwing out ideas. Most good artists (and I hope you chose a good artist) are very creative and can often times think in ways you can’t. What colors look good together, what lines may look good together, possible themes, etc.
I wanted something polynesian to represent the birthplace of Ironman and that’s what we did, but all I took in was a design/symbol I liked off of a visor I owned. He drew the rest and we plopped the M-Dot in the middle.
