Almost all of my designs can be put on tshirts. If you go to my site you can see more of my designs. Plus if you'd rather deal with me on purchasing artwork, just email me.
As for this design, I needed a good reference shot in a certain position and since it's a bitch to find that perfect position, I just took a pic of myself.
A lot of people referenced it to Christ which isn't necessarily a bad thing. But my intentions were more based on just the crucifixion position in general. And how at this position we are vulnerable to an attack. If that helps clear anything up.
