The Grand Arcanum of Scar

This is the tricept tattoo on the anime character known as "The Scar" "Scar" "The Alchemist Killer" and others, from Fullmetal Alchemist.
The tattoo on Scar is centered on the tricept. The Top of the tattoo begins just under where the tricept and deltoid meet and the bands at the side wrap around the top of the bicept. The forks at the bottom cross the elbow and the point touches one of three forearm bands wich I may post later. SPIOLER WARNING.....For more info on Scar [link]

Anyone familiar with FMA is welcome to comment constructivly on the layout of this tattoo. I didn't trace this I looked at about 10 screenshots from 4 or 5 episodes. The array that Marco and "The Exile" use isn't the tattoo that Scar's brother made. I noticed they were different. I found Marco's 6 point array and Ed's 7 point array and the The Grand Arcanum of "The Exile" but no tattoo. So I decided to take a stab at scar's tat (pun not intended).

I Used Inkskape.org and The GIMP.
