Here's a couple sketchs I did for some friends tatoos.
The first was a snake wrapped around a dagger. Nice, but changing the dagger to a sword and adding a backround I think makes a better statement.
The second was a simple lions head. How may of those have you seen? But by changing the mane to flames it adds a personal touch.
Hit up a local artistor maybe your tatoo guy and let him see what they can do for you.
